1. Write a word equation for photosynthesis.
photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced
chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 +
photosynthesis uses light energy to convert carbon dioxide into a carbohydrate.
2. What’s a biome? Name two of them.
A biome is a large region of Earth that has a certain climate and certain types of
living things. for example: tundra, forests, grasslands, and deserts.
2a. What biome would you expect to find a scorpion, a hawk, a rat, a snake, a cactus, and
a camel? Deserts
2b. Draw a possible food chain from this list of animals?
2d. Which is the producer in this list?
3. cactus
a. What is the difference between a food chain and a food web?
The food chain can be said as the straight and single pathway for the flow of energy in an
ecosystem, through different species of organisms. Food web, on the other hand, is defined
as the convoluted or complicated pathway of an ecosystem consist of numerous food chains
of the different trophic level, through which the energy flow.
b. Why is a food chain more specific than a food web?
The food web provides a better model of an ecosystem because the food web is a model
between MANY different consumers and producers in an ecosystem. While the food chain is
a model for just one consumer and producer, because energy is lost as it moves from
producers to consumers, the bottom level is the largest.
3. Why are phytoplankton and zooplankton important?
Photosynthesis by the phytoplankton accounts for up to half of global primary
5. Draw a simple energy pyramid and label it using the terms primary, secondary, and tertiary
consumer, and producer. How many trophic levels are there in your pyramid? Why is a pyramid
used to depict the energetic relationship between the trophic levels?
6. Define each of the following terms.
1. Biotic
2. Abiotic
3. Population
4. Community
5. Niche
6. Habitat
7. Invasive
8. Extinction
Biotic factors are the living parts of an ecosystem.
A non-living condition or thing, as climate or habitat, that influences or
affects an ecosystem and the organisms in it
Population means the number of people in a geographic area. It can also
be used for subgroups of people or animals.
Is a group of living things sharing the same environment.
Refers to the way in which an organism fits into an ecological
community or ecosystem.
A habitat is an area that is lived in by a particular species of animal,
plant, or other type of organism. It is the natural environment in which
an organism lives, or the physical environment that surrounds a
An invasive species is a species that is not native to a specific location,
and that has a tendency to spread to a degree believed to cause damage
to the environment, human economy or human health.
considered to be the death of the last individual of the species, although
the capacity to breed and recover may have been lost before this point.
9. Photosynthesis the process by which green plants and some other organisms use
sunlight to synthesize nutrients from carbon dioxide and water.
Photosynthesis in plants generally involves the green pigment
chlorophyll and generates oxygen as a by-product.
10. respiration
respiration is the movement of oxygen from the outside environment to
the cells within tissues, and the transport of carbon dioxide in the
opposite direction
11. Chlorphyll
Chlorophyll is any of several related green pigments found in the
mesosomes of cyanobacteria, as well as in the chloroplasts of algae and
7. How many types of craniates are there? Name them.
7 types,
1: X-ray tetra fish
2: Puppies
3: Amphibians
4: Reptiles
5: Birds
6: Mammals
7: Hagfish
8. What are the different kingdoms of living things?
Monera, Protista, Fungi, Plantae, Animalia,
9. How do you know a car isn’t alive whereas a dog is? Explain.
dog define life because have those characteristics sensitivity or response to the environment,
reproduction, adaptation, growth and development, homeostasis. and car not. Also, dog need water,
food ,breath and shelter.
10. How many different types of arthropods are there? Name them.
There are four major groups of arthropods
Chelicerata (includes spiders and scorpions)
Crustacea (shrimps, lobsters, crabs, etc.)
Tracheata (arthropods that breathe via channels into their bodies; includes insects and myriapods)
extinct trilobites – have heads formed of various combinations of segments, with.
11. What are the 5 main groups of plants?
Plants include familiar types such as trees, herbs, bushes, grasses, vines, ferns, mosses, and
green algae.
12. Draw the leaves of two different kinds of flowering plants below
13. Compare and contrast Mitosis and Meiosis in a human.
14. Correct order:
Plant Only
1. Ribosome
Plant & Animal
Is to synthesize proteins as directed in
the messenger RNA.
2. Large central
The main function of the large central
vacuole in plant cells is to provide
structural support.
3. Cell membrane
The cell membrane gives the cell its
structure and regulates the materials that
enter and leave the cell.
4. Cell wall
This is accomplished by the cell wall
creating a skeleton-like frame that enables
plants to grow vertically and develop a
rigid stem.
5. Mitochondria
Mitochondria are often referred to as the
powerhouse of the cell.
6. chloroplast
Chloroplasts are the part of plant and algal
cells that carry out photosynthesis.
7. Nucleus
The key function of the nucleus is to
control cell growth and multiplication.
