The correct answer is - phytoplankton.

The phytoplantkon is an organism that is at the bottom of the food chain, and it is the basis for the food chain in the marine environments. It is an organism that is an autotroph, which basically means that it manages to produce complex organic compounds from simple substances that are present in its surroundings, and very importantly, it uses mostly light or inorganic chemical reactions, thus the phytoplankton is a producer, and it is a main food source for large number of marine species.

How do invasive species change the diversity index?
Nuetrik [128]

UkoKoshka [18]

Answer: The options are not given, here are the options.

B. Periodic disturbances allow for coexistence.

C. Two species tended to use different resources.

D. The two species experienced interference competition and not exploitative competition.

The correct option C.

Two species tended to use different resources.

Explanation:

From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.

Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.

The bones in a bird are hollow, reducing its weight for flight. This is an example of which characteristic of life?
dimulka [17.4K]

The bones in a bird are hollow, reducing its weight for flight, this is an example of ADAPTATION. The adaptive responses emerge as a consequence of different environmental pressures.

<h3>Adapatation and environment</h3>

Adaptation is an evolutionary process by which organisms adjust to the environment in which they live.

For example, the bones in a bird are hollow because this adaptive feature enables them to fly.

Adaptations are a consequence of the process of natural selection, i.e., the differential survival and reproduction of the fittest organisms.
