where an organism lives-provides all it needs to live, grow, and reproduce (food, shelter, mates, water)
What is a habitat?
all the different populations that live together in an area (different species)
What is a community?
An organism that eats meat (lion)
What is a carnivore?
When prey increases predators ...
increase
the variety of a species in an area
What is biodiversity?
all living organisms (includes decaying things)
What are biotic factors?
nonliving things (sunlight, water, soil, climate, rocks)
What are abiotic factors?
An organism that only eats plants (zebra)
What is an herbivore?

decrease
What are threats to biodiversity?
Poaching, habitat fragmentation, habitat loss, etc.

What is a community?
An organism that will eat anything (racoon)
What is an omnivore?
When predators increase prey ...
decrease
How can we conserve species?
laws and regulations
number of individuals in a given area OR number of organisms/area
What is population density?
any biotic or abiotic factor that can limit the number of organisms or what type or organisms an environment can support (food, shelter, mates, water, temperature)
What are limiting factors?
made up of interconnected food chains
What is a food web?
When predators decrease prey ...
increase
What affects biodiversity?
area, climate, niche diversity, etc.
maximum number of organisms an environment can support
What is carrying capacity?
study of the environment and how all living things in it interact with each other and with abiotic factors
What is ecology?
What do the arrows on a food web show?
The flow of energy
Why are predator-prey relationships important?
because they drive evolution
Why is biodiversity important?
It gives us resources like medicine and food. Biodiversity had an economic value. There will also be fewer species to filter water, put nutrients in the soil, etc.
