Which is a man made ecosystem?

  1. Herbarium

  2. Tissue culture

  3. Forest

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

An ecosystem consists of biotic and abiotic components. Biotic components or living things include animals, plants, microorganisms. Abiotic components or nonliving things include air, soil, temperature. It is of two types, natural ecosystem and artificial or man made ecosystem. Examples of natural ecosystem include forest, aquatic ecosystem. Examples of man made ecosystem includes aquarium, zoo, botanical garden. In man made ecosystem, the plants and animals grow or survive outside their natural habitat in an artificial environment.

Thus, the correct answer is 'Aquarium.'

The largest unit in which gene flow is possible is?

  1. Organism

  2. Population

  3. Species

  4. Genes
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Gene flow is the passing over of genes from one population to another population. There are a various factors that affect the gene flow. The largest unit of population in which gene flow is readily possible is biological species. In species, successful interbreeding is possible which results in the successful reproduction and hence the gene flow. 

Thus, the correct answer is option C.

Multiple choice zoology meaning of life level of biological organization in animals introduction to tissues basics of ecology

All plants, animals and other organisms that make up a distinct natural community in any climatic region is known as the

  1. Biome

  2. Biounit

  3. Biomagnification

  4. Biological ecosystem
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A biome  is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. "Biome" is a broader term than "habitat"; any biome can comprise a variety of habitats. hile a biome can cover large areas, a microbiome is a mix of organisms that coexist in a defined space on a much smaller scale. For example, the human microbiome is the collection of bacteria, viruses, and other microorganisms that are present on or in a human body. A 'biota' is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-time scale spatiotemporal scales. The biotas of the Earth make up the biosphere.

So the correct option is 'biome'.
