An interaction favourable to both population, but obligatory to either, is
1 proto-cooperation
2 mutualism
3 commensalism
4 parasite
Explanation:
Exp. AProto-cooperation is the relationship between two species which is beneficial and favourable to both but not obligatory to both. Mutualism- It is the relationship between two or more individuals in which all are benefitted by each other. Parasite- The association between two organisms in which one organism benefitted and another organism is harmed.

Carnivorous animals - lions and leopards, occupy the same niche but lions predate mostly larger animals and leopards take smaller ones. This mechanism of competition is referred to as-
1 Competitive exclusion
2 Character displacement
3 Altruism
4 Resource partitioning
Explanation:
Carnivorous animals - lions and leopards, occupy the same niche but lions predate mostly larger animals and leopards take smaller ones. This mechanism of competition is referred to as resource partitioning. Resource Partitioning refers to the division of resources to avoid interspecific competition for limited resources in an ecosystem. It is an evolutionary adaptation that helps various species coexist in an ecological community. It helps in determining the effect of the addition or removal of a species in a particular habitat and the functioning of an ecosystem.

A sedentary sea anemone gets attached to the shell lining of hermit crab. The association is :
1 Amensalism
2 Ectoparasitism
3 Symboisis
4 Commensalism
Explanation:
A type of biological interaction is penicillium killing bacteria association of sea anemone and hermit crab is an example of commensalism. (Commensalism is the symbiotic relationship between two organism in which one benefited and another one neither benefited nor harmed). The sea anemone give the shelter or protection to the hermit crab and in return the hermit crab provides the food to the sea anemone. Ectoparasitism including lice, ticks, mites, flies are organism that inhabit the skin or skin surface of another organism host for several days.

Which of the following statements is incorrect?
1 lichen, an association of fungus and algae is an example of mutualism
2 those epiphytes which use other plants for support only and not for water or food supply and are examples of commensalism
3 sea-anemone on hermit-crab is an example of protocooperation
4 mutualism, protocooperation, commensalism cannot be included under symbiosis
Explanation:
All three commensalism, protocooperation, mutualism are types of symbiosis. Mutualism - Mutualism is an association of two different species in which they both are mutually benefiting each other and no one is harmed. It is a common type of ecological interaction. Proto cooperation - Proto cooperation is where two species interact with each other beneficially but a relationship is not necessary. Cooperating species do not depend upon each other for survival. For example - Predatory birds sit on cattle as this bird eats ectoparasites like leaches etc. Amensalism- Amensalism is an ecological interaction where one species causes harm to another organism without any benefits to itself. In this interaction, one species is harmed while the other is unaffected. - Mutualism or symbiosis is the mutually beneficial interaction between organisms of two different species, with non of the two capable of living separately. - In commensalism, one species is benefitted without the other being harmed.
