Ecology
Study of the relationship between living things and their environments
Ecologists study animals and their envorrionments
Interact
Process of organism acting upon one another or on the nonliving environment
Indirect or Direct
Deforestation

Clear Cutting a forest
Population
Group of the same kind of organism
School of fish
Humans
Community
All the populations that live in an area
Deer, grass, bears, mice, trees, birds,
Biodiversity
Many different species
High biodiversity=more stable and healthy environment
Habitat
Place where organisms live
Houses for people
Niche
Role or job of an organism in a habitat
Bears eat the deer to keep the population in balance
Host
The organism the is effected in a engine way by a parasite
Tape worm
Scavenger
Consumers that eat dead animals
Vultures
Decomposer
Organism that breaks down wastes or remains of other organisms
Worms, bacteria
Carrying capacity
Largest population that can be supported in an area due to limiting factors
Deer population increases so wolf population increases
Primary consumer
A consumer that eats a producer or autotroph
Usually a herbivore
Secondary consumer
A consumer that eats a primary consumer
Usually a carnivore
Tertiary consumer
This consumer is at the top of the food chain
Usually an omnivore
Food chain
Show how energy from food moves trough a population of organism
Rabbit eats grass then a hawk eats the rabbit
Food web
Shows how food chains are related
Energy pyramid
Shows how energy moves through an ecosystem
Only 10% of energy is transferred between the tropic levels and the other 90% is used for life in the prey
Competition
Struggle for resources
Animals compete for food
Symbiosis
Close relationships between different species
Deer get eaten by wolfs
Predation
When an organism kills another organism and eats it for energy
Wolf killing ant eating a deer
Predator
The animal that eats another animal lower than it on the food chain
Wolf(predator) eats Deer(prey)
