Daniel is studying feeding relationships in a neighborhood pond. He observes several organisms that feed on one another, and he
vichka [17]

So given the suggested food chain of algae-snail-sunfish-heron we can conclude that this food chain is heavily dependent on the process of photosynthesis.

The algae is the only of the organism that are directly dependent of the photosynthesis for their survival, while the snail, sunfish, and heron, and indirectly dependent on it.

Since we are talking about a food chain, in essence it means that all organism are connected through one another. So the algae perform photosynthesis for its own survival, the snail is using the algae is a food source, the snail is later eaten by the sunfish, and the sunfish goes on the menu of the heron.

If the algae, by some scenario, are not able to perform photosynthesis, than they will die off, and if they die off, than the snail will die off because of lack of food, if the snail dies off, along with it dies off the sunfish because of lack of food, and if the sunfish is out of the scene, the heron goes as well.

So we can conclude that the process of photosynthesis is of crucial importance for the survival of all four species, be it directly or indirectly.

Two similarities between the way<br> that a fungus feeds, and the way that<br> you feed.
Alexandra [31]

Answer:

Humans and fungi have a few similarities and a few differences.

Human's and fungi have similar feeding habits.

1- They are both heterotrophic (unlike plants, algae, etc. )

This refers to the fact of generating energy by consuming elements in the ecosystems.

This means that both get energy by feeding on other organisms.

2-Humans and fungi both cannot produce their own food using photosynthesis. They are not like plants.
