Ecology and Human Impact Review

What is an invasive/non native species?

• a species brought from one ecosystem to another that does not belong there

• a species that helps to keep the balance in an ecosystem

• a predator that helps balance the population

• a species that is helpful to humans

A group of the SAME SPECIES in an area makes up the

• community

• population

• ecosystem

• biome

A community is

• all the same species in an area

• all the LIVING THINGS (biotic factors) in an area

• all the living AND non living things in an area

• a large area with many ecosystems

All the LIVING (biotic) PLUS the NON LIVING (abiotic) things in an area makes up the

• population

• community

• ecosystem

• organism

The platypi, fish, and water plants are all

• abiotic factors in this ecosystem

• biotic factors in this ecosystem

• not important in the ecosystem

• not part of the ecosystem

Anywhere on Earth where life exists is collectively called the

• community

• ecosystem

• biome

• biosphere

When there is a lack of resources such as food, water, space, and sunlight, this is often called a

• limiting factor

• big hot mess

• healthy ecosystem

• population grower

Food is a limiting factor. What would happen to a snake population if all their food was killed off.

• the snake population would increase (go up)

• the snake population would stay the same

• the snake population would decrease

• there would be no change
