C Correct answer
Explanation
A.Plankton - a group of uncellular organisms
B.Nekton - aquatic animals that are able to swim and move independently of water currents.
C.Plankton and nekton - a group of uncellular organisms and quatic animals that are able to swim and move independently of water currents.

Which is not true regarding ecosystem?

  1. Self sufficient unit

  2. Cyclic exchange of materials between living beings and environment

  3. Only requirement is input of energy

  4. Characterized by a major vegetation type
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An ecosystem is not just an energy input system; it is a complex, self-regulating unit that involves the interaction of biotic and abiotic components. The claim that the only requirement is energy input ignores the necessity of nutrient cycling and biological interactions.

  4. Mobius

D Correct answer
Explanation

The term biocenosis was coined by Karl Mobius in 1877. It describes the interacting organisms living together in a habitat (biotope). Based on the concept of biocenosis, ecological communities can take in various forms zoocenosis for the faunal community, phytocenosis for the flora community and microbiocenosis for the microbial community.

Therefore, the correct answer is option D.

  2. Niche

  3. Biomes

  4. Environment

B Correct answer
Explanation

Nice is the ecological role and space that an organism fills in the ecosystem. The ecological niche involves both the place where an organism live and role that an organism carries out in its habitat e.g. A plant growing in garden along with soil, climate, sunlight, nutrients etc.

Which is the best example of interaction of biotic and abiotic factors of ecosystem?

  1. Sunlight

  2. Water

  3. Land

  4. Forests
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Forests provide excellent introduction to the foundational concepts of ecology, since they are among the most structurally and biologically diverse of the planets ecosystems. Forests are built upon highly complex relationships between living and non-living components. In a forest, abiotic factors include fundamentals such as sunlight, moisture, nutrients, bedrock and topography. Biotic components are the living members of the system. A defining trait of an ecosystem is the cycling of nutrients and energy between organisms and their environment, and it is these abiotic components that provide the foundation for interaction between members of ecological communities.

Living organisms has not effect on the abiotic factor around them in an ecosystem.

  1. True

  2. False

  3. Ambiguous

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

Living organisms constantly take in or give out various abiotic factors. Thus, each biotic factor affects the quality of the abiotic factor around itself and thus affects the lives of the other biotic factors with which it share the ecosystem.
