These are species that are not native to an area, but do well and become established there

This relationship involves one species benefitting while harming the other one negatively

These species are the most abundant in an ecosystem.

This is each phase in food chains; can include producers, primary consumers, and apex predators.

This is the position or special job/service that an organism has in an ecosystem

Beavers are an example of this; an organism that helps to alter an ecosystem

This is an ecosystem that is able to withstand any pressures and support all of the organisms within it

This is the act of cities creating new buildings on the outskirts of their areas in the suburbs; can destroy ecosystems

The complete dying out of a species

When energy is transferred from one level of the food chain to the next, 10% is always lost. This is called:

Glucose + Oxygen --> Carbon Dioxide + Water

This includes all the different varieties of species and organisms within an ecosystem, which need to be protected

The total weight of all the biotic elements in an ecosystem

Members of a species who live in the same area and can reproduce to make offspring

Controlled breeding that is done by humans in an enclosed area (like a zoo), for rare/endangered species

The part of earth that includes the crust, rock, landforms and ground

A relationship, like with the bird and the giraffe, where both parties benefit

The tropics are an example of this place; where there is a great variety of different species

When dangerous toxins build up in organisms and are passed on from one level to the next in a food chain

Lack of food, too little space, and polluted water are examples of this

All of the populations gathered in an ecosystem are called this

Ecosystems that are found in water

When everything is all balanced in an ecosystem - the number of organisms, the amount of nutrition available and the space is enough

The gradual changes in an ecosystem over time, usually after a disturbance (like a dam changing a forest)

All the biotic and abiotic factors in an area that are interconnected with one another

This is the breaking down of glucose into energy, when there's no oxygen to help

A species who is extremely important and vital to an ecosystem (it may not be the biggest in number)

Ecosystems that are on land

Carbon dioxide and methane are examples of these, that can cause the earth to warm up

This is the process of cutting down trees but not replanting more in their place

Water, temperature, oxygen and rocks are all examples of these types of things in ecosystems

When nitrogen oxide and sulfuric acid go into the clouds from the water cycle, they come back to earth in this damaging form

These species are not native to a particular area and can cause great damage to ecosystems

All the water areas on earth

This type of population increase is not sustainable because there are an insane amounts of organisms in a small area. There will be too much competition

This is the overuse of various resources or organisms, that causes some species or ecosystems to be endangered

The layer of gases that surround the earth and keeps us warm and insulated

This is the total amount of organisms that are able to live and thrive in an ecosystem given the number of resources available to them

Any time an ecosystem is ruined, this occurs

This is all of the lifeforms and living areas on earth

This is the species that does the hunting of another organism for it to consume

This is a major issue right now: the loss of species from extinction, which can harm the sustainability of ecosystems

This is the organism that is hunted and consumed by another

This relationship is where one species fully benefits, and the other species is not harmed nor do they benefit

This cycle includes: nitrogen gas being changed to ammonium from bacteria so plants can use it, then it goes back in the atmosphere when it is released from dead animals/plants

This cycle includes: evaporation, condensation, precipitation, and then groundwater.

Biodiversity can be measured by:

Producers are the most important element of a food web because:

What happens to the energy when it goes to the tertiary/apex consumer

What is an example of keystone species?

Why are hummingbirds good examples of showing how ecosystems are connected?
