The term “
fitness
” in evolutionary biology means the ability of an organism to pass on its genetic material to its offspring. Biological or “Darwinian” fitness is being able to live long enough to reproduce and keep the population or species alive.
What term describes the ability of an organism to survive and reproduce in its environment?
Fitness
is the ability to survive and reproduce. This is made possible through the use of adaptations which make an organism better suited to its environment.
Which term describes a feature that allows an organism to better survive in its environment?
An adaptation
is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.
What term refers to the role an organism has in its environment?
Concepts to Be Covered
The community and the abiotic factors make up the ecosystem. An organism lives in its habitat within a community. The role or job of an organism within a community is
its niche
.
What is ability to reproduce?
Reproduction refers to the production of offspring by organized bodies. The offspring is produced as a new individual organism from the parent(s). It is one of the fundamental attributes of a living thing. Reproduction is a demonstration of the ability of an organism to produce a
new
organism referred to as offspring.
What are analogous structures?
Analogous structures are
features of different species that are similar in function but not necessarily in structure
and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.
What best describes survival of the fittest?
Survival of the fittest is a simple way of describing how evolution (the process by which gradual genetic change occurs over time to a group of living things) works. It describes the
mechanism of natural selection
by explaining how the best-adapted individuals are better suited to their environment.
Is the ability an organism has to survive in a particular environment?
An adaptation
is any heritable trait that helps an organism, such as a plant or animal, survive and reproduce in its environment.
What are three examples of traits that will increase an organism’s chance of survival?
Survival may include
getting food, building homes, and attracting mates
. Traits that allow a plant, animal, or other organism to survive and reproduce in its environment are called adaptations. Natural selection occurs when: There is some variation in the inherited traits of organisms within a species.
What are organisms examples?
The definition of an organism is a creature such as a plant, animal or a single-celled life form, or something that has interdependent parts and that is being compared to a living creature. An example of an organism is
a dog, person or bacteria
.
What is the study of interactions between organisms and their environment?
Ecologists
Study the Interactions of Organisms and Their Environment.
What type of organisms are found in community?
Community, also called biological community, in biology, an interacting group
of various species
in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
What are the animals can reproduce in large number?
Selina Heppell, head of the Department of Fisheries and Wildlife at Oregon State University, says other fish known to have high numbers of eggs include
sturgeon
(up to 2.5 million eggs for Atlantic sturgeon) and large tuna (bluefin tuna can produce 10 million eggs a year).
What are the 3 types of reproduction?
- Asexual Reproduction.
- Sexual Reproduction.
What are two asexual reproduction examples?
Modes of Asexual Reproduction
Organisms choose to reproduce asexually by different means. Some of the asexual methods are
binary fission (e.g. Amoeba, bacteria)
, budding (e.g. Hydra), fragmentation (e.g. Planaria), spore formation (e.g. ferns) and vegetative propagation (e.g. Onion).
What is an example of analogous structures?
Analogy, in biology, similarity of function and superficial resemblance of structures that have different origins. For example,
the wings of a fly, a moth, and a bird
are analogous because they developed independently as adaptations to a common function—flying.
