Living Things
What the letter 'm' stands for in the MRS C GREN mnemonic.
What is movement?
A community of living things of multiple species and their environment.
What is an ecosystem?
In the chain Grass → Rabbit → Hawk, what eats the rabbit?
What is the hawk?
The definition of a food web
What are multiple interconnected food chains?
An animal that only eats plants
What is a herbivore?
Two characteristics that all living things share.
Any two from movement, respiration, sensitivity, cells*, growth, reproduction, excretion, nutrition.
What Māori concept describes the life force or health of an ecosystem?
What is mauri?
The main source of energy in any food chain.
What is the sun?
The organism at the 'top' of a food web
What is an apex predator?
An organism that makes its own food
What is a producer?
A seed lying dormant does not appear active. Which characteristic of living things helps show it is still alive?
What is growth or respiration?
Planting native trees along a stream is an example of what type of activity?
What is a sustainable activity?
The organism in a food chain that creates its own food.
What is a producer?
The reason why one prey species going extinct might not also drive a predator to extinction.
It may have other food sources in the web.
What is a decomposer?
Respiration in living things is the process of using O2 or CO2 to do what?
What is processing glucose* into a short-release energy form such as ATP?
If pollution enters a river, what is likely to happen to its mauri?
It decreases/weakened.
Create a food chain involving 4 animals. You have 30 seconds.
Any valid answer.
Which is usually more stable: a food chain or a food web?
What is a food web?
The classification of each organism: grass, rabbit, hawk.
What are producer, herbivore, carnivore?
Cars can move and use fuel for energy, what features do they lack that stops them from being considered alive?
What are reproduction, growth, and/or cells
Explain one adaptation that helps an animal survive in its habitat.
Any valid adaptation and explanation.
The reason all food chains begin with a producer
Producers capture energy from the Sun and provide energy for the rest of the chain.
Explain why removing one species can affect many others in a food web.
Species depend on one another for food and energy.
The reason there are usually more producers than top predators in an ecosystem?
Energy is lost at each feeding level, so many producers are needed to support fewer predators.
