Q

Type?
Heterotroph

A

Consumer that is a A heterotroph is an organism that can’t make its own food and must get energy by eating other plants and animals.
Examples of heterotrophs include:
Herbivores: Eat only plants
Carnivores: Eat only other animals or meat
Omnivores: Eat both plants and animals
Decomposers: Break down dead organisms or their waste products into nutrients for soil
Detritivores: Eat detritus which is dead or decaying matter

What does competition mean in terms of a food web?
That means the two animals will compete for the same resources
26
Can an organism be a consumer at multiple levels in an ecosystem?
An organism can be a different trophic levels this occurs when an organism is an omnivore which means it consumes both plants and animals
27
Why are decomposers important to the food web and ecosystem?
They decompose the dead organisms so they can give nutrients to the soil so they can make more green plants
