Where an organism lives
Who is responsible for almost all modern day environmental issues?
Humans
Habitat Destruction
Destroying the home of an organism. This could happen because of deforestation

How are humans causing the loss of biodiversity?
Killing orgnaisms
What's another word for Bioaccumilation?
Biomagnification
What is bioaccumilation?
When poisons build up in the food chain. The higher up you go in the food chain the more poison there is
What decreases the higher up you go on the energy pyramid?
Energy and biomass

Mutualism, Commensalism, and Parasitism
Mutualism
Both organisms benefit
Commensalism
One organism benefits and the other doesn’t care
Parasitism

Carbon Cycle
Carbon is an element that is in all living things on earth. It cycles the earth mainly in the form of Carbon Dioxide and Glucose
What are the 3 ways Carbon Dioxide gets into the atmosphere?
Respiration, burning fossil fuels, and open burning
What is the main way Carbon is removed from the atmosphere?
Photosynthesis
How are humans releasing excess fossil fuels into the atmosphere?
Burning fossil fuels
Greenhouse Effect
Too much carbon dioxide causing the Sun’s radiation to be trapped on the earth which is causing the earth’s temperature to rise
What is another word for the Greenhouse Effect?
Global Warming
What does Global Warming cause?
Glaciers melting and ocean levels rising
Population Growth
Populations will grow unchecked until they are limited by limiting factors
Limiting Factors
Resources like water, space, food, etc. That a population can run out of
What are the 3 population curves?
Carrying Capacity, J-Curve, and S-Curve
Carrying Capacity
The number of organisms an ecosystem can support
J-Curve
This population grows extremely fast (exponential growth). The population uses up all the resources and will crash and all die out
S-Curve
This population grows until it reaches it carrying capacity. Then it will stabilize over the carrying capacity
What makes the Predator and prey population growth are opposite of each other?
Carrying Capacity
When the predator is up
The prey is down
When the prey is up
The predator is down
Birthrate
The number of people born each year
Birthrate=Deathrate
No population growth
Birthrate>Deathrate
Population will grow
Birthrate<Deathrate
Population will decrease
