Question

what is population interaction?

Answer 1

Types of Population Interaction

In nature, all organisms and their populations interact with one another to some degree or the other. That is how an ecosystem works perfectly! This population interaction is generally between two different species populations. These interactions can be beneficial or neutral or detrimental. Accordingly, there are six types of population interaction.

Answer 2

What is Population Interaction?

The species and the individual of the ecosystem are never independent. They are always interlinked. The ecological community is formed by interaction between individuals of two or more species. This interaction is termed as population interaction where individual of one species interact with the individual of another species. It can be for feeding, beneficial, or for harming.

Types of population Interaction

◆ Positive interactions:

1. Mutualism/Symbiosis: Here, both the organism gets benefitted from each other. Example: In lichens the algal part helps in photosynthesis and the fungal part provides support. Pollination by animals.

2. Commensalism: Atleast one species gets benefited from this interaction. Example: epiphytes, epizoite.

3. Protocooperation: Here both the species gets benefited passively. Example: sea anemone.

◆ Negative Interactions:

4. Parasitism: Here one organism take shelter of another organism for nutrients and affect the host's metabolic activities. Example- malaria parasite in human and lice.

5. Predation: One organism feeds on other for energy; forming the food web of the ecosystem. Example: lion eating deers.

6. Amensalism: Here, one species gets harmed while other remains neutral. Example: salvia leucophylla and formation of antibiotics.

7. Competition: In this interaction, No organism gets benefited. It marks the competition between two species for same resources. The competition happens between organisms of same niche and guild. Due to this, the growth of the population will never reach the carrying capacity of the ecosystem. Example: Competition between lion and tiger for food.
