____ take longer to decompose so they need to be finely cut
Grace [21]
Hello there!

Let's take for example plastic, plastic would take a good while for it to decompose. It wouldn't make sense for it to be "food produce" because food does decompose very quickly. Wood could be the answer, but wood wouldn't take that long for it to decompose, all it could use is some constant water and rain, and then the wood would then give old and just decompose. But even thought that is the case, wood cuttings would be the answer.

Vegetable peels would not take a long time.Most likely, they are probably to fastest in this list above. So, based from your options, your correct answer would be (wood cuttings).

(option a) would be your answer.

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

<h3>What is a food chain?</h3>

Food chain is the sequence of matter and energy transfers as food from one organism to another.

Food chains interconnect locally into a food web as most organisms consume more than one type of animal or plant.

The number of organisms decreases on movement from producers to consumers in a food chain. This happens due to decreased energy levels at higher trophic levels.

Thus, it can be concluded that this is the main reason behind the number of snakes consumed as compared to other organisms.
