What animals eat both producers and consumers
omnivores
movement of organisms into a range
immigration
Plants are
Primary producers
The branch of biology dealing with interactions among organisms and between organisms and their environment is called
ecology
The repeated movement of water between Earth's surface and the atmosphere is called
Water cycle
An interaction in which an animal feeds on plants is called
herbivory
a natural resource that can be replenished naturally over time, allowing its sustainable use without depleting its availability.
renewable resource
The algae at the beginning of the food chain is a
primary producer
The simplest grouping of more than one kind of organism in the biosphere is
community
Ways the carbon is cycled in the ecosystem
photosynthesis, burning of fossil fuels, decomposition, cellular respiration
Suppose that a species of toads is introduced into a new environment in an attemp to reduce the population of insects. The toad has no natural predators in the new environment. The toad population would most likely
increase exponentially
a natural resource that exists in a fixed amount and cannot be replenished by natural processes quickly enough to keep up with human consumption, meaning it's finite and can be depleted.
nonrenewable resource
Heterotrophs are considered as what
consumer
If an organism does not require sunlight; what process does it use to make food?
chemosynthesis
A symbiotic relationship in which both species benefits
mutualism
Only 10 percent of the energy stored in an organism is passed on to the next trophic level. Of the remaining energy, some is used for the organism's life processess and the rest is
eliminated as heat
One species benefits and the other is unaffected
commensalism
Which trophic level would get the least amount of energy
Tierary/quartary
An orgnanism's niche is
the role it plays in its environment
deforestation, pestiside and fertilizer use, factories, cars
How do most primary producers make their own food? Be specific
by using light energy to make carbohydrates
one organism benefits and the other is harmed
paratism
A bird stalks, kills and then eats an insect.
consumer
What is a climax community?
Final stable stage of an ecologyical succession
The difference between primary and secondary succession
primary begins on newly exposed surfaces
secondary begins on soil
