All the living and nonliving things that surround a living thing
environment People, other animals, plants, water, air, soil,weather
All the living and nonliving things in an area form this
A group made of the same kinds of individuals
population One plant or animal
All the populations that live in the same place and have at least one thing in common
community Forest Coastal swamp
Most living things on Earth get the energy to live from this
Any living thing that can make its own food
producer Green plants Algae
An animal that eats other plants and animals
An animal that eats only plants
An animal that eats only other animals
An animal that eats both plants and other animals
A living thing that feeds on wastes and on the remains of dead plants and animals
Living thing that absorbs nutrients from living plants and dead plant materials
Fungi (FUN – jy)
These tiny decomposers can only be seen with a microscope
What would happen if there were no decomposers on the earth?
Earth would be covered with dead plants and animals.
An environment that meets the needs of a living thing
How a living thing interacts with its habitat
Niche (NICH) How it gets food, shelter, reproduces, cares for young, and avoids danger
The movement of food energy in a sequence of living things
Food chain Every food chain begins with a producer.
Consumers that are eaten
prey They are hunted.
Consumers that eat prey
predators They are the hunters
What would happen if there were no predators?
There would be an imbalance Some animals would starve and become extinct.
Several food webs that overlap form this
Food web One kind of producer may be food for several kinds of consumers
Shows how each level of a food chain passes on less food energy than the level before it
What would happen if a large number of organisms in the base level of the pyramid change or are killed by drought?
The whole food chain is affected. If the first level is affected, many in the higher levels will starve.
The living parts of an ecosystem
biotic Plants and animals
The nonliving parts of an ecosystem
abiotic Sunlight, water, air, soil
The amount of rainfall and sunlight in a region, and the repeating patterns of temperature
climate Abiotic factor
