Interactions of Organisms in an environment
limits and population size
growth and population size depends on physical conditions and on resources available to the organism. If they unlimited resources, living things could produce populations of infinitive size.
limiting factors
are factors in the environment that limit the size of populations. they can be both abiotic as well as biotic.
biotic factors
prey
are organisms or animals killed for food by the predator.
predators
are organisms (consumers) that kill and eat other animals.
abiotic factors examples:
ph. level of soil, sunlight intensity, dissolved oxygen in a pond, temperature range, minerals and water in the soil, etc.
Competition
is the struggle for resources among organisms. it keeps the size of that species' population balanced and in check. The size of the population remains stable over time due to competition.
Composition
Ecosystem
the
environment
is every living and nonliving thing that surrounds an organism.
biotic
factors are the living influences organisms in an environment or the environment itself.
population
is all the organisms in a species that live in the same area.
abiotic
factors are the non living influences organisms in an environment or the environment itself.
the
biosphere
is the biologically inhabited parts of the planet, all of the earth's combined ecosystems.
habitat
is the specific environment or home of the organism or species.
ecosystem
is the "ecological system" or any portion of the environment. Made up of living things that interact with one another.
roles and interactions
energy pyramids
are diagrams that illustrate the transfer of energy through food chain or web.
food webs
are diagrams that show the complex feeding relationships among producers, consumers, and decomposers.
Scavengers
like vultures are consumers of dead organisms. dead bodies will be broken down by decomposers though.
Organisms that feed of of dead animals for their survival are called
decomposers
. they are organisms that recycle and return unconsumed energy back into the environment.
Carnivores
are heterotrophs that consume other animals.
herbivores
are heterotrophs that rely on and survive on plants' tissues.
food chains
are diagrams that illustrate relationships between the prey and the predator.
heterotrophs
are organisms that must acquire food through the consumption of other organisms. also called
consumers
.
autotrophs/producers
are photosynthetic organisms that make their own food through the energy of the sun.
Biodiversity
biodiversity
is the term that describes the enormous variety of life on earth
In addition, ecosystem services—benefits that humans receive from natural environments—are often greater in highly diverse places
