Question

The two interacting species live closely together in
A. Mutualism, competition and amensalism
B. Predation, parasitism, and competition
C. Predation, parasitism, and commensalism
D. Predation, competition, and commensalism

Answer 1

Hint:
Species interactions create the basis for many ecosystem properties and functions, such as food webs and nutrient cycling. The character of these interactions can differ depending on the environmental conditions in which they appear and the evolutionary context. These interactions can be intra-specific (interactions between the same species) or inter-specific (interactions with different species).

Complete step by step answer:
Competition is defined as the direct or indirect interaction between organisms that leads to a change in fitness when they share the same resource. The result usually has negative impacts on the weaker competitors. Predation is a biological interaction in which a predator hunts and feeds on prey. Because the predator depends on the prey as a source of food, their populations are intertwined.
Symbiosis is an interaction defined by two or more species living intentionally in direct contact with one another. The term "symbiosis" includes a broad range of species interactions but typically refers to three major types: commensalism, parasitism, and mutualism. Mutualism is a symbiotic interaction in which both individuals benefit from the association. Commensalism is an interaction where one individual benefits and the other is neither benefited nor harmed. Parasitism occurs when the parasite, benefits from another host while harming the host during the process. Parasites feed on host tissue or fluids and can be seen within or outside of the host body. Parasitism, predation, and commensalism share a common feature; the two interacting species live closely together.

Option ‘C’ is correct

Note:
Another interaction similar to predation is herbivory, where an individual feeds on a photosynthetic organism such as a plant or algae, perhaps killing it. An important difference between predation and herbivory is that herbivory does not always lead to death.
