Ecology I
These living things break down organic matter. E.g. bacteria and fungi are called these.
What are decomposers?
What is biotic factors
What is an adaptation of koalas?
What is camouflaged fur, claws, nocturnal?
What is a food web?
What type of adaptation is camouflage?
What is structural?
The process by which some living things make food from the sun's energy
What is photosynthesis?
An organism that lives on or in another organism and hurts it.
What is parasitism
Why is the amount of energy passed on to consumers decreasing at each level?
What is energy lost as heat, movement and undigested materials?
Which group of organisms always starts a food chain or web?
What is a producer?
a group of organisms of the same species that live in an environment
What is a population?
Organisms that rely on other organisms for their energy
What are consumers?
non living parts of an environment
What are abiotic factors?
If producers have 1000kJ of energy, how much energy will be passed on to the organisms that eat them?
What is 100kJ (10% rule)?
What is it called when different organisms are fighting for the same resource?
What is competition
where an organism lives -includes both biotic and abiotic factors
what is habitat
Organisms that eat both plants and meat
What are omnivores?
In this relationship, both species benefit
What is mutualism?
What are the 3 types of adaptations?
What is behavioural, structural and functional
What type of adaptation is sweating?
What is functional?
any relationship where two species live closely together
what is symbiosis
Organisms that only eat plants
What is a herbivore?
In this case, one organism benefits, the other is neither helped nor harmed.
What is commensalism?
Give 3 examples of abiotic factors
What is temperature, light and water?
Draw the food chain:
Termites eat grass
Termites are eaten by echidna
Echidna are eaten by dingoes
What is grass -> termites -> echidna -> dingo

D. Top order consumers
What is C. producers?
