What is a producer/autotroph?
An organism that makes its own food in an ecosystem.
300
What is commensalism?
A relationship where one species benefits and the other is not affected.
300
What is a community?
All of the populations of different species that live in the same geographic area at the same time

An ecosystem has producers, first order consumers, second order consumers, and third order consumers. Pollution in the ecosystem kills all of the first order consumers. Which organism(s) will most likely survive?
Producers.

Bacteria living in your body helps you break down food an obtain nutrients. In return, the bacteria get a safe place to live. What type of relationship is this?
Mutualism.

A tick feeding on the blood of a dog is what type of relationship?
Parasitism.
400
What is an ecosystem?
A community (biotic factors) and the abiotic factors in that environment.

Why is less energy available in the second trophic level than the first?
Some of the energy can be given off as heat.

What is a Decomposer?
Organism that receives its food/energy from dead or decaying matter by CHEMICALLY breaking it down.

Grass-->Beetle-->Frog-->Snake-->Hawk. Given the following food chain, describe what would happen if the species in Trophic Level 3 went extinct?
The snake and hawk populations would die/decrease, and the beetle population would increase. The increase in the beetle population would eventually cause a decline in the grass population.
