the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources.

Ecological Footprint

200

The type of growth that occurs when there is a limiting factor

Logistical Growth

Feeds on animal and plant remains and other dead matter.
What is a detrivore.
200
Collection of different populations that live together in an area.
What is a community.

The type of growth that occurs in ideal conditions

Exponential Growth

300
Links all food chains in an ecosystem.
What is a food web.
300

A collection of all organisms that live in a particular place, together with their physical environment or aboitice factors

What is an ecosystem.

300

The biggest threat to biodiversity on Earth

Births and Immigration

400
Energy for all life processes come from here.
What is the sun
400
The combined portions of the planet in which all life exists.
What is a biosphere.
400

Excessive use, of species that have economic value is a factor increasing the current rate of extinction.

Overexploitation

400

What happens to a predator population when the prey population increases and why? 

The predator population would increase because there would be more food (prey) available to keep the population alive

500

A natural disaster is an example of what type of limiting factor

Density- Independent Limiting Factor

500
Heterotrophs that eat both plants and animals.
What is an omnivore.
500
Each step in a food chain or web.
What is a trophic level.
500

Describe Invasive Species risk to the environment

The harm the environment as they thrive and overpopulate a native environment. They usually result in native organism death
