Science of self control in an ecosystem is called as

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

  1. Synecology

  2. Autecology

  3. Cybernetics

  4. Edaphology

Show answer
Correct Option: C
Explanation:
Synecology is the branch of science which deals with the study of plants or animal groups or communities.
Autecology is the study of particular species of the living forms.
Cybernetics is the interdisciplinary study of the structure of complex systems. It is a science of automatic control system in any complex structure like living things and machines.
Edaphology is the study of the role of soil in the environment and its contribution to the living world.
Thus, the correct answer is option C.

Show answer
Correct Option: A
Explanation:

In ecology, a community or biocoenosis is an assemblage or association of populations of two or more different species occupying the same geographical area and in a particular time.

Ability of the community to come back quickly to its original form is

  1. Resistance

  2. Resilience

  3. Disturbance

  4. Heterogeneity

Show answer
Correct Option: B
Explanation:

The capability to bounce back and to use physical and economic resources effectively to aid recovery following exposure to hazards can be termed as community resilience.

The major sub-divisions of biosphere are

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

  1. Soil, water and hydrosphere

  2. Soil, atmosphere and lithosphere

  3. Atmosphere, lithosphere and hydrosphere

  4. Atmosphere, lithosphere and air

Show answer
Correct Option: C
Explanation:

The biosphere is defined as the part of Earth, which is habituated. There are different subdivisions of biosphere. These are known as -

1. Hydrosphere 
2. Lithosphere 
3. Atmosphere. 
They interact with each other and do not occur alone. They provide a crucial role in the existence of organisms.

Natural habitats that were once large and connected have become more fragmented due to human activities. Wildlife corridors between the fragments of habitat are necessary to maintain wildlife habitat and natural areas.
Which of these is a benefit of wildlife corridors?
I.Allows young adult animals to access a new range.
II. Improves genetic fitness as adult animals interact with potential mates in other areas. 

III. Allows plants and animals to colonize new habitat as the climate changes.

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

  1. I only

  2. II only

  3. III only

  4. I and III only

  5. I, II and Ill

Show answer
Correct Option: D
Explanation:
Wildlife corridors are the areas that link wildlife habitats but are separated by human activities such as roads.
Hence, wildlife corridors between fragments of habitat will allow young adult animals to access a new range and allows plants and animals to colonize new habitat as the climate changes.
So, the correct answer is 'I and III only'.

Correct Option: B

A man-made microecosystem is

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

  1. Plants grown in a pond

  2. Crop field

  3. Tank formed naturally in your courtyard

  4. Lake in a forest

Show answer
Correct Option: B
Explanation:

Ecosystem is made up of living and nonliving components. It is of two types, natural ecosystem and artificial ecosystem. Natural ecosystem is also called as macroecosystem. Artificial ecosystem is called as microsystem. Microecosystems can exist in locations which are precisely defined by critical environmental factors within small or tiny spaces. A man-made microecosystem is crop field. It is independent of solar energy. 

Thus, the correct answer is 'Crop field.'

Which of the following communities are more vulnerable to invasion, by outside animals and plants?

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

  1. Tropical forests

  2. Mangroves

  3. Temperate forests

  4. Oceanic island communities

Show answer
Correct Option: D
Explanation:

Oceanic island communities are more vulnerable to invasion by outside animals and plants than those of main lands. These islands include high volcanic-based islands like Hawaii and low coral islands like Marshalls. These areas are susceptible to invader impacts. This is due to lack of natural competitors and predators which control populations in the ecosystems.  

Thus, the correct answer is 'Oceanic island commuities.'
