and non-living things

Biotic
Living things in the environment, such as humans, plants,
birds, animals, and insects.

Species
a group of organisms that reproduce with each other
Population
Members of species that live in the same
area and share resources
Biotic
Living things in the environment, such as humans, plants,
birds, animals, and insects.
Abiotic
Non-living physical features of the environment, such as air,
rocks, water, and temperature.
Population
Members of species who live in the same
area and share resources
Community
Populations of different species interacting and sharing resources
Needs of living things
water
food
habitat or living conditions
Oxygen and exchange gases.
Symbiotic Relationships
where two species live closely
together in a relationship
Mutualism
both organisms benefit from the relationship.
Commensalism
one organism benefits and the other organism appears
neither to gain nor lose from the relationship.
Parasitism
one organism benefits and the other organism is harmed
from the relationship
A parasite
organism that obtains nourishment or other life support from a host.
Adaptation
characteristic that helps an organism survive
and reproduce
Structural adaptations
physical features like the beak on a bird or the fur on
a rabbit. These features help them survive.
Behavioral adaptations
anwser with examples
bird calls, migration and looking both
ways before crossing a street are
behavioral adaptations.
Adaptation
Natural Resources
how we meet our basic needs
Non-renewable resources
cannot be produced, grown, or generated
Renewable resources
are replaced by natural processes
Consumers
Any organisms that must seek out and eat
Herbivores
animals that eat plants
Carnivores
animals that only eat other animals
Omnivores
animals that eat plants and animals
Scavengers
feed on dead or decaying matter
Decomposers
feed and break down organic matter
Producers
organisms that
use energy from the sun to
make their food
Cellular Respiration
chemical reaction that occurs within the cells of all living
things

What is a food chain
food chain is a diagram that shows
how energy moves
