CAN DO List – Year 9 Biological Science
Components of an Ecosystem
I can:
Define the terms Biotic and Abiotic with relation to Ecology
List 5 Abiotic factors in ecosystems
Explain how each abiotic factor is important in ecosystems
Classify ecological factors as either biotic or abiotic
Define the following ecological terms: Habitat, Ecology, Ecosystem, Population,
Community, Biodiversity.
List 4 Biotic factors in Ecosystems
Explain how the following biotic factors influence ecosystems: Competition, Predation,
Commensalism, Mutualism
Define the following ecological terms: Producer, Consumer, Decomposer, Autotroph,
Heterotroph, Photosynthesis
Explain how Dissolved Oxygen is important in aquatic ecosystems
Describe the relationship between dissolved oxygen and temperature
Energy Flow through Ecosystems
I can:
Define the following ecological terms: Food Chain, Food Web, Trophic Level, biomass,
Pyramids of Biomass, Pyramid of numbers, Pyramid of energy
Create a food web to show interrelationships between organisms and the flow of energy
Explain how energy initially enters ecosystems
Describe how energy flows through ecosystems
List 3 ways energy is lost from ecosystems
Explain why food chains are rarely more than 4 or 5 feeding relationships in length
Create a pyramid of numbers and pyramid of biomass using specific food chain data
Use a pyramid of biomass and a pyramid of numbers to explain feeding relationships in
ecosystems
Explain how one change in a feeding relationship can impact other areas of the same
ecosystem.
Matter Cycles in Ecosystems
I can:
List the 3 states of matter
List 3 examples of matter that cycle through ecosystems

ecosystems
List the main parts of the water cycle
Explain the following water cycle processes: Evaporation, Condensation, Precipitation,
Transpiration, Infiltration
Describe how a water molecule can travel through the water cycle
List the main parts of the carbon cycle
Explain the following carbon cycle processes: Photosynthesis, Respiration, Combustion,
Decomposition
Describe how a carbon molecule can travel through the carbon cycle
