  1. Edge species

  2. Link species

  3. Keystone species

  4. Pioneer species

  5. Successional species
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Keystone species is a species, which has a significant and disproportionately large influence on the community structure and characteristics. It has often considerable low abundance and biomass as compared to dominant species. Removal or decrease in number of keystone species causes serious disruptions in structure and function of community.

Which of the following types of organisms occupies more than one trophic level in a pond ecosystem?

  1. Phytoplankton

  2. Fish

  3. Zooplankton

  4. Frog
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In an aquatic ecosystem, fishes can consume phytoplanktons and other producers. In such a system, fishes will be primary carnivores or primary consumers or herbivores as compared to the grazing food chain. Some bigger fishes can consume smaller fishes. In this case, bigger fishes will act as secondary consumers or secondary carnivores feeding on primary carnivores. Thus, fishes can occupy more than one trophic levels. Phytoplanktons will always be producers and zooplanktons will always be primary consumers. The frog will always act as secondary consumer feeding on primary consumers i.e., insects. Thus, the correct answer is option B.

A man - made ecosystem is

  1. Less in diversity

  2. More in diversity

  3. Man does not make ecosystem

  4. More stable then natural ecosystem
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Man made or artificial ecosystems have low stability. Because usually man is interested in only a few economically beneficial species only and only those species will be used by man to create an ecosystem e.g., agriculture field is a man made artificial ecosystem having only those plants which are economically beneficial. Thus, the correct answer is option A.

Niche is altogether a different concept. Niche is related to ecological role of a species.
