C Correct answer
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.

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.

  1. I only

  2. II only

  3. III only

  4. I and III only

  5. I, II and Ill

D Correct answer
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'.

A man-made microecosystem is

  1. Plants grown in a pond

  2. Crop field

  3. Tank formed naturally in your courtyard

  4. Lake in a forest
Reveal answer Fill a bubble to check yourself
B Correct answer
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?

  1. Tropical forests

  2. Mangroves

  3. Temperate forests

  4. Oceanic island communities
Reveal answer Fill a bubble to check yourself
D Correct answer
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.'
