living parts of an ecosystem. Includes things that are alive, WERE alive but are now dead, and things that come from something living.
what is Biotic
a large region of Earth that has a certain climate and certain types of living things.
what is Biome
organisms that make their food (autotrophs), they do not eat other organisms.
what is a Producer
a specific order of organisms where one organism feeds on the preceding one.
what is a Food Chain
the variety of life in the world, or a certain ecosystem or habitat.
what is Biodiversity
non-living parts of the ecosystem. Includes things that are NOT alive, NEVER were alive and never will be alive, and things that do not come from something living.
what is Abiotic
a collection of the same species of organism in a particular area.
what is Population
organisms that must eat other organisms for food/energy.
what is Consumer
a system of overlapping food chains with arrows that show the direction energy flows in an ecosystem.
what is Food Web
the first species to grow and colonize an area of land.
what is Pioneer Species
a small, localized habitat within a larger ecosystem, like a decomposing log in a forest, having conditions that sustain a limited range of animals and plants
what is Microhabitat
all the living things in a particular area.
what is Community
organisms (bacteria/fungi/etc.) that eat and breakdown dead organisms and release nutrients back into the soil.
what is a Decomposer
an ecosystem that has developed over time and reached a stage where its number of plant and animal species (and other organisms) does not change much from year to year or remains stable.
what is Climax community
elements of an ecosystem that control the number of organisms that can live/survive in that ecosystem (amount of food, water, shelter, etc.).
what is Limiting factors
a collection of all the biotic factors in an area as well as the abiotic factors they depend on.
what is Ecosystem
the part of the earth where life exists.
what is Biosphere
starts on bare rock, soil is formed from plants that begin to grow, in time, larger plants grow and animals move in.
what is Primary Succession
when an ecosystem that already had soil and a community of organisms changes (or gets destroyed: fire, flood, etc.) and then a new ecosystem takes over.
what is Secondary Succession
an organism at the top of the food web with no natural predators above it. Nothing regularly hunts and eats them, they do that to other organisms.
what is Top/Apex Predator
the process in which plants make sugar and oxygen from sunlight, carbon dioxide and water (this happens in chloroplasts).
what is Photosynthesis
a pyramid that shows how energy flows through a community.
what is Energy Pyramid
the process of one community in an ecosystem being replaced over time by a more advanced community.
what is Ecological Succession
the obviously better college than UT
what is A&M (sorry)
