The variety of species within a given area.
What is Species Diversity?
A species that is naturally from an area or naturally grows in that area.
Native species
This is also known as the hydrologic cycle.
Water cycle
The sun is the most important part to start this cycle.
Water cycle
This term refers to the total number of different species present in a given area.
What is Species Richness?
A species that is not naturally from the area and causes harm
When plants release water from their leaves to go into the atmosphere this is called ____________.
Transpiration
Nitrogen from dead animals or excretion from animals is converted into ammonia. The ammonia then can be used as a plant nutrient. What is this called?
Ammonification
When there is low species evenness, there are species who are ____________.
dominating the ecosystem
A species that is not from the area but has over time started to coexist with native species
Non-native species
Process where bacteria converts atmospheric N2 into ammonia.
Bacterial Nitrogen Fixation
Carbon is found in the ________ as CO2 and in the _______ as dissolved CO2 gas.
atmosphere, ocean
We are comparing two ecosystems. Ecosystem 1 has 5 different species of trees and Ecosystem 2 has 7 different species of trees. (1) has a species that is significantly more present than the others, making up 80% of the tree population. (2) has about the same proportions of each species throughout the ecosystem. Which has higher RICHNESS and which has higher EVENNESS?
Richness - 2
Evenness - 2
True or False: A species can be labeled as non-native and then eventually be labeled as invasive.

An ecosystem that is less stable would have what?
Lower Species Diversity
Invasive species tend to ___________ native species and take their resources and can even make them die off.
outcompete
This cycle is the only one that occurs on land AND what process starts the cycle?
Phosphorus, Weathering
_______ from fertilizers in the _____ and _____ cycles can cause _____ _____, (build up of algae on the water) which can be harmful to humans, the environment, and marine animals.
