Question

An intimate relationship between two species in which co-evolution and adaptation occur is
A. Competition
B. A Community
C. Predation
D. Symbiosis

Answer 1

Ecosystem is the whole of the species of every kind on our planet Earth. There are units that make this large biome possible. The change in the basic unit will affect all the rankings in the hierarchy thereby, affecting the largest ranking. Ecology is the sum of all the different varieties in our
surroundings. The manner in which organisms reside therefore becomes very important to understand.

Step by step answer: Ecological hierarchy means the ranking of the ecological members. Every species existing in the universe make the ecology. So the hierarchy places them in order- individual, population, community, ecosystem, biome, biosphere. The ecosystem is made up of many communities spread in larger areas. They all have different characteristics but live in the same atmosphere under the common universe. Community is the gathering of different populations. Different species populations make the community of an area. The community prevails in various types of interactions between two organisms, this can be beneficial or harmful.
-Option A: Competition: In this interaction, both organisms fight with each other for the requirements and resources. They can either kill each other or have a dominancy fight. This does not help In co-evolving.
-Option B: A Community: An ecology formed of different organisms is a community.
-Option C: Predation: This interaction involves killing the other organism for food. The predator attacks its prey. The prey tries to escape but it fails, it becomes the food for the predator.
-Option D: Symbiosis: It is a long term interaction. There are different types of symbiosis - one of them is mutual. In this, both organisms benefit from each other. The co-evolution and adaptation occur due to intimate proximity.
So the answer is option D: symbiosis

Note: Biodiversity is important for the ecosystem. Every species has an important role in the maintenance of ecology. The disasters can exploit the ecosystem but if the biodiversity is high and rich, the ecosystem will recover or heal fast.
