Life exists only in the biosphere- the thin layer encircling the Earth where air, land, soil, and water exist.
Abiotic factors
Soil type, rainfall, sunlight, heat, topography, etc. in a ecosystem. These factors are referred to as non-living, or abiotic.
Biotic factors
Living things in an ecosystem. Ex. Plants, animals, insects, microorganisms.
The place where an organism (plant, animal, or microorganism) naturally lives or grows is called its habitat, which is defined largely by environment factors.
Earth's biosphere can be divided into smaller regions called biomes that support similar climates and types of plants, for example: grassland, tundra, boreal forest, and desert. The state of Michigan is located within the Temperatures Deciduous Forest Biome. Similar to "climate type."
A group of organisms of the same species living in a particular area at a particular time.
All living things that share the same living area and resources is a community. This is similar to a community of people all living in a certain geographical area.
A community of organisms interacting with one another and the nonliving environment. Environmental conditions such as variations in sunlight, air, moisture, heat, topography, and soil type all influence the variety of living things in a given ecosystem.
Any form of life.
A group of similar and related organisms (for example, blue jays and robins are separate species.)
Eat plants and other animals.
Animals who eat other animals.
Plant eaters.
An organism that eats to survive.
Use the Sun to make energy- rich molecules.
Consume wastes and dead organisms.
Consumers who capture and eat other consumers.
A consumer captured and eaten by another consumer.
The amount of biological or living diversity per unit area. It includes the concepts of species diversity, habitat diversity and genetic diversity.
The transfer of pollen from male reproductive structures to female reproductive structures in plants.
An insect that carries pollen from one flower to another.
Habitat loss
The destruction of habitats that usually results from human activities.
Colony Collapse Disorder
A mysterious disease that causes adult bees to disappear from their hives without a trace. It may be caused by: parasites, fungus, viruses, bacteria, pesticides, poor nutrition, or stress.
Native Species
Species that normally live and thrive in a particular ecosystem.
Introduced Species
Species moved by humans to new geographic areas, either intentionally or accidentally.
Ecosystem Balance
Represents an equal number of species in the environment; disturbance causes imbalance.
Genetic Variation
Differences among individuals in the composition of their genes or other DNA segments.
Species Diversity
Variety of different kinds of organisms that make up a community.
Ecosystem Diversity
variety of habitats, communities, and ecological processes in the biosphere.
Genetic Diversity
sum total of all the different forms of genetic information carried by all organisms living on Earth today.
The disappearance of all members of a species from Earth.
Endangered Species
A species in danger of becoming extinct in the near future.
Threatened Species
Species that is likely to disappear.
Introduced Species
Any organism that was brought to an ecosystem as the result of human actions.
Native Species
Species that have naturally evolved in an area.
Acid Rain
Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water.
Ozone Depletion
thinning of Earth's ozone layer caused by CFC's leaking into the air and reacting chemically with the ozone, breaking the ozone molecules apart.
Conservation Biology
application of biology to counter the loss of biodiversity.
Habitat Restoration
Returning a natural environment to its original condition
Captive Population
A population of organisms that is cared for by humans.
Reintroduction Programs
Programs that return captive organisms to an area where they once lived.
