Answer 1

Answer: Symbiosis in which each organisms benefit ecological niche.

Step-by-step explanation:

Symbiotic relationship is an interaction between organisms living together in which either they both benefits, or one benefit or parasitic in which the predator cause harm on the prey. Symbiotic relationship can either be mutualistic I.e each benefits from each other, predation or parasitic I e one benefits and cause harm in another.

Answer 2

Option:Symbiosis in which both organisms benefit ecological niche.

Step-by-step explanation:

• Symbiotic association between any living organism:

The symbiotic association is the connection between any organisms, which are either benefited by each other or the relationship can be very negative for the either one, or it may be neutral in nature for both the organisms living inside a symbiotic relationship.

The symbiotic association between the different organisms are of four different natures or levels,which are as follows:

1. Mutualism: Inside the relationship or connection between any number of organisms in which there is mutual benefit for both the organisms, is called as the mutualism. For example, the insecticides living in the plants roots or any part of its body.
2. Parasitism:Such a symbiotic relationship is which between any two living organism either one of them is benefited while the other one is harmed by its effect. For example, the tape worms in the living body.
3. Predation: It is more simple to understand as the prey is hunted down and killed in order to fulfill the needs of the predator.For example the lion and the impala.
4. Commensalism: The type of association between the living organism in which one of the organism is benefited, while other is neither benefited nor harmed. For example the marine life on the back of the crab's body.
