Answer:

Heterotrophic species that eat organisms from different trophic levels

Explanation:

Humans are examples of primary and secondary consumers because we are able to eat different types of living forms, thereby acting in the food chain as primary consumers (eating plants) in certain conditions and as secondary consumers (eating animals) in different conditions. Many heterotrophic organisms act at different levels by feeding primary producers and primary consumers based on specific trophic strategies. In consequence, the classification between primary and secondary consumers is arbitrary since it varies according to the trophic strategy adopted by the organism.

Pachacha [2.7K]

Answer:

a prezygotic barrier

Explanation:

Both wild tigers and lions are said to be reproductively isolated.

Reproductive isolation is defined as the existence of barrier between organisms of different species such that they cannot reproduce.

The mechanisms of reproductive isolation varies. While some act to prevent the formation of zygotes (in case of mating) between organisms of different species, some ensures that the resulting zygotes are invalid.

Reproductive isolation mechanisms that act to prevent fertilization and formation of zygotes are referred to as prezygotic mechanisms while those that ensure that invalid zygotes result (in case of successful fertilization) are referred to post zygotic mechanisms.

<em>The natural differences in the ranges of wild tigers and lions ensure that both animals do not mate with each other, let alone results in zygote. This is a form of pre-zygotic reproductive isolation mechanism.</em>
