What is ecology?
The scientific study of interactions among organisms and between organisms and the environment.
What is Biotic and Abiotic?
Biotic and Abiotic factors determine the survival and growth of an organism and the productivity of the ecosystem in which an organism lives.
What do plants release?
Plants release O2 into atmosphere as a waste product
What are food chains?
A food chain is a series of steps in which organisms transfer energy by eating and being eaten.
what is Ecosystem?
a collection of all organisms that live in a particular place together with their nonliving environment.
What is the biosphere?
Contains the combined portions of the planet in which all of life exist, including land, water and atmosphere
What is Biotic Factors?
Living Factors that influence an ecosystem
What is the energy flow?
The flow of energy through an ecosystem is one of the most important factors that determines the ability to sustain life
What is the food web?
A network of complex feeding relationships among the various organisms in an ecosystem
what is a Biome?
a group of ecosystems that have the same climate and similar dominant communities.
What are species?
Group of organisms so similar to another that they can breed and produce fertile offspring
What is Abiotic Factors?
Physical, non-living factors that influence an ecosystem
Captures energy from sunlight or chemicals and use that energy to produce food.
What is the Energy Pyramid?
A diagram that shows the amount of energy or matter contained within each trophic level in a food chain/web
what is Ecological Succession?
a series of predictable changes in an environment
What is population?
Same species and live in same area
What is a habitat?
The area where an organism lives is called its habitat.
What is Heterotrophs?
Organisms that rely on other organisms for their energy and food supply.
succession that occurs on the surface where no soil exists
Examples of Pioneer Species
Lichen
What is a community?
Different populations that live together in a defined area
What is a niche?
A niche is the full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions. It is an organisms’ occupation.
What are parasites?
A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host.
What is energy flow?
Energy flows through an ecosystem in one direction from the sun to autotrophs (producers) and then to heterotrophs (consumers).
what is Succession?
following a disturbance that destroys a community without destroying the soil.
