Download autotroph: self-feeding or producer, is an organism that produces

autotroph: self-feeding or producer, is an organism that
produces complex organic compounds (such as
carbohydrates, fats, proteins) from simple substances
present in its surroundings, generally using energy from light
(by photosynthesis) or ingorganic chemical reactions
(chemosysthesis). Plants, algae, many bacteria
heterotroph: nutrition is an organism that cannot fix carbon
and uses organic carbon for growth. This contrasts with
autotrophs, such as plants and algae, which can use energy
from sunlight (photoautotrophs), or inorganic compounds
(lithoautotrophs) to produce organic compounds suchas
carbohydrates, fats, and protein from inorganic carbon
dioxide. Animals, fungi, many bacteria
abiotic factors: pertaining to any non-biological factors that
play a role in an organism’s environment; non-living
environmental factors. Example: A forest fire is an example
of an abiotic factor.
biotic factors: an influence or effect created by an organism;
an effect of an organism’s actions within an environment
source of energy (the sun): Sunlight is Earth's primary source of
energy. The solar constant is the amount of power that the Sun deposits per unit
area that is directly exposed to sunlight.
organism (species):
In biology, an organism is any contiguous living
system (such as animal, fungus, micro-organism, or plant).
population: A population is all the organisms that both belong to the same
group or species and live in the same geographical area.
community:
A group of organisms or populations living and interacting with
one another in a particular environment.
ecosystem: An ecosystem is a community of living organisms
(plants, animals and microbes) in conjunction with the nonliving
components of their environment (things like air, water and
mineral soil), interacting as a system.
Producers are organisms, like green plants, that produce
organic compounds from inorganic compounds. These are
also a type of autotroph. Then green plants, for example, are
eaten by consumers in this case, grazing animals like the
zebra.
An autotroph is an organism that makes its own food from
inorganic substances. It is then eaten by a consumer if it is a
plant for example.
A consumer is the organisms that obtain nutrients from other
organisms. This is also a heterotroph.
A heterotroph is an organism that cannot synthesize their
own food and must obtain it ready made.
A decomposer is an organism of decay. These are also
called saprobes. They break down the remains of dead
animals and plants, releasing the substances that can be
used by other members of the ecosystem.
