Key area 2 – Energy in Ecosystems Learning Intention: We are learning to understand the structure of the ecosystem, and how organisms interact with in the ecosystem. We are also learning to understand about the importance of nutrient cycling in the ecosystem. I can: T State the role of the producers, primary consumers, and secondary consumers in the ecosystem. Explain what is meant by herbivore, carnivore, omnivore, prey and predator. Describe the effects of removing one species from a food web on the number of the other species. State that energy can be lost from a food chain as heat, in movement, and in undigested materials. State that the pyramid of numbers shows the numbers of organisms at each link in the food chain. State the numbers of each organism decrease as you move up the food chain. State that size of each organism increases as you move up the food chain. State that pyramids of biomass shows the mass of organisms at each link the food chain. State that a pyramid of energy shows the energy present in the organisms at each link the food chain. State that a pyramid of energy always has a pyramid shape. State that only 90% of the energy is lost at each link in the food chain. State that there is a limited supply of nutrients in any ecosystem. State that decomposers are responsible for returning nutrients to the soil. State that plants and animals require nitrogen to produce proteins. State that peas and clovers contain bacteria in their root nodules that can convert nitrogen gas to nitrates. Describe the stages of the nitrogen cycle. State that fungi and bacteria are responsible for converting proteins into ammonia then nitrite and then nitrate. State that nitrifying bacteria increase the levels of nitrate. State the root-nodule bacteria convert nitrogen gas to nitrate. State that denitrifying bacteria decrease the levels of nitrate by converting nitrate to nitrogen gas. State that competition occurs when resources are in short R R supply. Give examples of what plants compete for. Give examples of what animals compete for. State that interspecific competition occurs between different species in the same ecosystem. State that intraspecific competition occurs between members of the same species. Explain why intraspecific competition is more intense than interspecific competition. State that intense competition might result in death of an organism or force it to leave the ecosystem.

Key area 3 – Sampling techniques and measurement of abiotic and biotic factors Learning Intention: We are learning to measure species diversity and abiotic factors in an ecosystem, the common error with the techniques and how to minimise these errors. We will also learn how to use keys to identify organisms. I can: Explain why it is impossible to count every organism in an ecosystem. State that representative sampling requires several samples to be taken and the larger the area the more samples need to be taken. Describe what quadrats are used for and how to use them properly. Explain the limitations and errors that occur when using a quadrat. Describe how to minimise these errors when using a quadrat. Describe what pitfall traps are used for and how to use them properly. Explain the limitations and errors that occur when using a pitfall trap. Describe how to minimise these errors when using a pitfall trap. State that an abiotic factor is a non-living condition that affects the growth and distribution of organisms in an ecosystem. Give examples of abiotic factors. Describe how to measure light intensity, what common errors are and how to minimise them. Describe how to measure temperature, what common errors are and how to minimise them. Describe how to measure pH, what common errors are and how to minimise them. Describe how to measure soil moisture, what common errors are and how to minimise them. State that keys are used to identify organisms. Identify organisms using a paired statement key. Identify organisms using a branched key.

Key area 4 – Adaptation, natural selection and the evolution of species Learning Intention: We are learning to understand what mutations are and how they contribute to variation. We are also learning to understand how adaptations contribute to survival. We will also learn about the process of natural selection and how it has contributed to the formation of new species. I can: T Explain what mutations are. State that mutations are rare, random and spontaneous. Give examples of environmental conditions (mutagenic agents) that can increase the rate of mutation. State that mutations can be advantageous (create new alleles) or disadvantageous (e.g. sickle cell anaemia, cystic fibrosis). State that all members of population show variation. State that variations allow organism to evolve over time in response to changing environmental conditions. Explain what is meant by adaptations. Give examples of special adaptations that allow organisms to survive in extreme environments. Give examples of behavioural, physiological and structural adaptations. State that all organisms produce more offspring than the environment can support. State that variation will exist between the offspring and those better suited to the environment will survive to breed. State that the alleles which allowed them to survive will then be passed on to their offspring. State that natural selection is an ongoing process that happens over long periods of time. Using the peppered moth as an example, explain the process of natural selection. State that a species is a group of organisms that can interbreed and produce fertile offspring. Explain what is meant by speciation. Describe the order of events that occur during speciation. List the three isolation methods in speciation.
