Evolution of population

1. Maximizing Reproductive fitness
2. Low r value
3. Minimizing Darwinian fitness
4. Both B and C

Which of the following will breed more than once in their life cycle?

1. Pacific salmon fish
2. Bamboo
3. Cuckoo
4. Both A and C

Life History traits

1. Evolved with the constraints imposed by mainly the Abiotic Factors of that habitat
2. An intense research area
3. Both A and B

None of these

The biological community can have

1. An isolated population of plants which doesn't depend on animals and microbes
2. An isolated population of animals which doesn't depend on plants and microbes
3. An isolated population of microbes which doesn't depend on plants and animlas
4. No isolated population is possible there.

By a particular interaction in a population one species was harmed while other was benefited. Such interaction is called as

1. Competition
2. Predation
3. Parasitism
4. Both B and C

The interacting species live closely together in which of the following interaction?

1. Parasitism, Predation and Amensalism
2. Commensalism, Amensalism
3. Mutualism and Competition
4. Parasitism, Predation, Commensalism

Predation can be thought as

1. Prey's way to control it's population
2. Nature's way of transferring energy to higher trophic levels.
3. Nature's way of controlling predators food chain
4. Predator's way of controlling prey's energy level

In broad ecological context, which of the following can be a predator?

1. Seed eating sparrow
2. Lion
3. Tiger
4. Crow

Predators cannot perform

1. conduit for energy transfer
2. control prey species
3. make ecosystem stable
4. Allow the herbivore to be full of energy fixed by autotrophs.

Why does the exotic species become invasive and start spreading fast?

1. It gets better nutrition there.
2. Because of lack of competition from other exotic plants
3. Because of lack of natural predator
4. Because of successful establishment of food web.
