A population that seems to grow faster over time with no lack of resources
The H in HIPPCO
What is Habitat Destruction?
The purpose of the leaf litter lab
What is to understand how matter is decomposed, appreciate the amount of life in small things or to observe primary consumers
Bald eagles have the ability to eat fish, small mammals and birds. If disease reduced the population of otters what would happen to the ecosystem?
What is more fish and birds would be eaten, which would increase the amount of things that fish and birds eat.

A population reaches carrying capacity
What is when it is no longer increasing in number, steady, or balanced with another population
The primary greenhouse gas

What is temperature?
In the owl pellet lab we knew that 90% of the energy was lost between trophic levels as heat. Why didn't anyone get exactly 90%
