Ecology
Living things in the environment

Non-living things in the environment
Abiotic factors

Ecosystem
The place where an organism lives
Habitat
Anything that restricts the number of individuals in a population
Limiting factors
The largest number of individuals of one species that an ecosystem can support over times
Carrying capacity
The highest rate of reproduction under ideal conditions
Biotic potential
Can make their own food/energy
Autotrophs
Getting energy from the sun
Photosynthesis
Getting energy from chemicals and minerals
Chemosynthesis
Types of heterotrophs
Herbivore, carnivore,omnivore, decompser
Simple model of the feeding relationship in an ecosystem
Food chain
Series of overlapping food chains;more realistic
Food web
Any closer relationship between species we provide food, shelter, support, or transportation
Symbiosis
Type of symbiosis, both organisms benefit. Example:
lichen made up of an algae and a fungus.
Mutualism
One organism and benefits, and the other harm. Example, ticks, or worms in animals.
Parasitism
An organism benefits, and the other is not affected. Example, clown fish and sea anemone
Commensalism
The role of an organism within the community
Niche
List three things that make up the biosphere
- Top portion of Earth’s crust
- All the water
- Atmosphere
Four types of consumers
