Species
What is an organism that lives on or in a host organism and gets its food from or at the expense of its host?
Parasites
What shapes an Ecosystem?
Organisms that live together in ecological communities
what is a CO2 Cycle?
Its a nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.
Mushroom is a kind of fungi that breed on the ground or the dead material
Decomposers
same species and live in same area
Population
an ecosystem in one direction from the sun to autotrophs (producers) and then to heterotrophs (consumers)
Energy Flow
The survival and growth of an organism and the productivity of the ecosystem in which an organism lives.
Biotic and Abiotic
the flow of energy through living things within an ecosystem
Energy Flow
succession that occurs on the surface where no soil exists
Succession
different populations that live together in a defined area
Community
a series of steps in which organisms transfer energy by eating and being eaten
Food Chains
Living Factors that influence an ecosystem
Biotic Factors
Algae, along with plants and some bacteria and fungi
Autotrophs
Common examples of pioneer species include bacteria, lichen, mosses, and fungi
Pioneer Species
a collection of all organisms that live in a particular place together with their nonliving environment.
Ecosystem
A network of complex feeding relationships among the various organisms in an ecosystem
Food Web
Physical, non-living factors that influence an ecosystem
Abiotic Factors
they consume producers or other consumers like dogs, birds, fish, and humans
Heterotrophs
the combined portions of the planet in which all of life exist, including land, water and atmosphere
Biosphere
a group of ecosystems that have the same climate and similar dominant communities.
Biome
a graphical representation of the energy found within the trophic levels of an ecosystem
Energy Pyramid
the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere.
Carbon Cycle
the final user of the food, making you a consumer of food
Consumers
atomic, molecular, cellular, tissue, organ, organismal, group, population, community, ecosystem, landscape, and biosphere
