Living Things and the Environment. Key Words. Habitat Biotic Factors Abiotic Factors Populations Species Community Single Organism Ecology. Habitats. Organisms live in a specific place within an ecosystem.
Organisms live in a specific place within an ecosystem.
An organism obtains food, water, shelter, and other things it needs to live, grow and reproduce from its surroundings.
This place is known as a habitat.
Single ecosystems may contain manyhabitats.
In a forest ecosystem, mushrooms grow in the damp soil, rabbits live on the forest floor, and termites live under the bark of tree trunks
Organisms live in different habitats within the ecosystem.
Organism interacts with both the living an non-living things in its environment.
The living parts of an ecosystem are called
Grass, plants, hawks, eagles, worms, fungi, bacteria – biotic factors
Non-living parts of an ecosystem
Affect living things
Abiotic Factors Are:
A species is a group of organisms that are physically similar and can reproduce with each other to produce fertile offspring.
All species within a particular area are referred to as a population.
All the pigeons in New York City
all the daises in a field
You can not use all the trees in a forest
there are different species of trees
Areas for population can be as small as a single blade of grass to as big as the entire planet.
Populations can move from place to place. Blue fin whales will move to different parts of the ocean.
Ecosystems contain more than one type of organism
All the different populations that live together in an area make up a community
To be considered a community the organismsmust live together and interact with each other.
They may interact by using the same types of shelter, food, or resources.
Smallest unit: living organism
Next: Population of species
Then: Populations of different species
live together in community
Finally: The community and the abiotic
factors together in ecosystem
