Explanation:
Mutualism is defined as an interaction between individuals of different species that results in positive (beneficial) effects on per capita reproduction and/or survival of the interacting populations.
The eubacteria is photosynthetic, like a plant is.
Answer:
A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.
Prey or predation is a biological interaction where a predator (an organism, often an animal) kills and eats its prey (another organism).
Like a mouse getting caught and eaten by a bird of prey (Eagles, hawks, etc.)
