Question

1. what is symbiosis and how does it affect organisms?

Explanation:

Symbiosis is a close and long - term biological interaction between two different species. There are three main types: mutualism (both species benefit), commensalism (one benefits, the other is unaffected), and parasitism (one benefits at the expense of the other). It affects organisms by influencing their survival, reproduction, and evolution. For example, in mutualistic symbiosis, the interaction can enhance the fitness of both species, while in parasitism, the parasite can harm the host's health and survival.

Answer:

Symbiosis is a close, long - term interaction between different species. It can be mutualistic, commensalistic, or parasitic and affects organisms' survival, reproduction, and evolution.
