YEAR 7 SCIENCE –ECOSYSTEMS AND CLASSFICATION UNITS. Complete the following: Section A- Werribee observation and evaluation questions below. Section B- Eat or be Eaten Student trail questions. Section C- Classy adaptations question sheet. Evaluation question SECTION A 1. In the table below, list 4 species of animal you see on the bus safari tourdescribe their behaviour and explain how it may be an adaptation to its environment.(remember all of the factors an animal needs to survive in its habitat: MRSGREN, and the adaptations may be structural, physiological or behavioural). ANIMAL Giraffe Camel Zebra Bison Description of behaviour How behaviour adapts animal to its environment. It was eating and walking around. Its front legs would spread really When it ate its front legs spread wide apart so it could get food. Its apart. long neck and tongue also helps it get food from the trees. The Mum and Dad were lying The sand made them think that down and the 2 daughters were they were in their natural habitat. walking around. They also have big flat feet so they don’t sink into the sand. It was frolicking and eating at some The have grindy teeth to eat stages. grasses. They have gaps between their teeth to store food. It just sat there and ate food. It They are big and strong so they can was a boring animal. fight the other males to get the girls. 2. Following your safari bus tour select and name your favourite animal. My favourite animal is: Rhino Comment on what you think the outcomes might be for this animal in the wild if the following conditions occurred in their natural habitat: a. Humans were allowed unlimited hunting rights: Humans do already hunt them for their horns even though it is illegal. b. Trees were removed and a number of roads were created across the animal’s habitat, dividing it into numerous smaller isolated areas. It would find it much harder to get food as there would be a lot more predators in the same area. This would limit the amount of food, water and shelter. 3. How would this impact on the food web of the African savannah when a. All male lions were killed: There would be not as many animals hunted and it would be a completely different scenario. The numbers of animals would increase. b. A decade of drought occurred in their habitat: Lots of animals would die and many species become extinct. 4. Explain why conservation programs are necessary in many areas of Africa. Because people are hunting animals which eventually means they would become endangered and then extinct. 5. Can you name any native Australian animals that are having their populations preserved by conservation programs? Name at least two and state what is being done to preserve them. Crocodiles- There is lots of crocodile farms and they have made hunting them illegal. This is so they don’t become extinct. Cassowary- They have made hunting them illegal and they have preserved them in zoos and wildlife parks around Australia. 6. What studying/training have the zoo staff had to help them understand the needs of the animals at Werribee zoo? What type of food you feed them. Their behaviour. Breeding season. 7. What things do the zoo staff have to understand and be able to do in order to manage the animals in the zoo environment? Give examples of the specific needs of three animals: Animal Animal needs which zoo keepers have to meet. Lion The lion Keeper, who feeds them. Zebra They have to feed it and protect it. Giraffe They have to make sure it doesn’t feel threatened and they need to feed them. 8. What benefits are gained from us studying animal ecosystems, behaviour and habitats? If we grow up and decide to be a zoo keeper we will have some idea on what to do. Also if we go to the zoo we will be able to understand the animals a lot more. SECTION B – Eat or Be Eaten Your challenge was to observe grassland animals interacting together and find examples of the adaptations they possess to obtain and digest food and avoid being eaten themselves. 1. Skull analysis Write in the features that are present on the skulls that you observed during the Learning Experiences program. Animal Dentition Mandible (lower jaw) Eye position Diet Type of Consumer Zebra Molars Long Lion Canine teeth Short Side Grasses and roots. Primary Front Meat Tertiary 2. Using specific examples compare the adaptations of a herbivore with a carnivore for finding food and avoiding predation in the table below. Examples of adaptations for finding food Examples of adaptations for avoiding predation Herbivore They just eat plants, grasses and other vegetation. They are fast and can hide in some places. Carnivore They hunt down animals. They will eat any type of meat they can get. They are very fast and have long sharp teeth. 3. Develop a food web in the space below that includes organisms that you observed at the Zoo. Include a key to identify and label a producer, a primary consumer, a secondary consumer and tertiary consumer within your food web. Food web: Key: 4. Describe the impact of domestic livestock on a food web in the African savannah. 5. Outline what Zoos Victoria is doing to help the Melako community in Kenya to reduce the impact of their livestock on the wild animals of the savanna. SECTION C – Classy Adaptations Animals are classified in many different ways. Classification is often based on an animal’s adaptations. Adaptations evolve over millions of years and are directly related to the survival of animals in their habitats. Please classify the following animals by observing their behaviours, identifying their features and looking at the design of their enclosures. Common wombat Orangutan Australian fur seal Platypus Baboon Vertebrate Western lowland gorilla Vertebrate Vertebrate Vertebrate Vertebrate Vertebrate Mammal Australia Mammal Africa Mammal Indonesia Mammal Australia Mammal Australia Mammal Africa Forest and bush Jungle or Jungle or forest areas forest Rivers and river beds Jungle and forests Place in habitat In its burrow In trees In trees Water and burrow In trees Body temperature 32-37 degrees Celsius 35.5 degrees Celsius 29-30 degrees Celsius Ocean and coastal areas In the water and on coastal land areas 37.7 degrees Celsius 32 degrees Celsius 36-39 degrees Celsius Grass, snow tussocks and other plants Fruit, grass, shoots, roots and insects Their diets vary month to month Fish and squid The live with relatives They live in a Colony Shrimp, crayfish, insect larvae and worms They are solitary It is an omnivore so it eats a range of foods They live in troops Swinging from tree to tree Forward Endangered They swim to move They walk or swim It walks on all fours Forward Least concern Side Least concern Forward Least concern Classification Invertebrate/ Vertebrate Class Country of origin Bioclimatic zone Period of activity Diet Social structure Locomotion Eye position Conservation status (IUCN) Ambassador They are solitary They live in groups called troops They walk It walks on on the sole its front of their feet knuckles Side Forward Least Critically concern endangered for which Zoo Victoria’s Conservation Campaign? Which of the above classifications would Zoos Victoria be most concerned with and why? The Gorilla, mainly because it is critically endangered and if we don’t do anything they will become extinct. EVALUATION QUESTION: Answer the following as an argumentative piece of writing. It should be in paragraphs. Make sure you cover the following key points: a. In your opinion, should animals such as Australian natives and African natives be kept in zoos? b. Describe in what situations you think it is acceptable/necessary and when it should not be allowed. c. Use examples as evidence to support your ideas, and give detailed reasons why they should /should not be kept in zoos. d. Explain what you would see as the future of some species if they were not kept in zoos.(use an example) EVALUATION QUESTION: YOUR ANSWER. I believe that native animals to Africa and Australia should be kept in zoos only if they were endangered. It should be allowed if there are people hunting them for their skin, horns etc. But if they are not being hunted and they are not endangered I see no reason for them to be in zoos. Animals like Rhinos should be protected in zoos because poachers are hunting them for their horns. They don’t just take the horns they kill the animals. This is why some animals should be permitted in zoos. If you don’t keep some species in zoos they will eventually be hunted and there would be nothing left. All the animals would become extinct.
