Food chains showcase clear picture of who is eating who. But when we try to use them to characterize entire ecological communities i.e food web, certain problems arise. For example, a species may sometimes consume numerous prey types, or be consumed by several predators at various trophic levels. To even more accurately describe these interactions, we should use a food web, a chart that demonstrates most the trophic — eating-related — relationships within an ecosystem among different species.
Arrows point from a species consumed on food chains to the creature that consumes it. Some organisms that eat species from more than one trophic stage, as shown in the food web below. Opossum shrimp, for an instance, consume both primary producers as well as primary consumers. Primary producers demonstrated with green, primary consumers with orange, secondary consumers with blue while tertiary consumers with purple.
Fungi get their nutrition by absorbing organic compounds from the environment. Fungi are heterotrophic: they rely solely on carbon obtained from other organisms for their metabolism and nutrition. Fungi have evolved in a way that allows many of them to use a large variety of organic substrates for growth, including simple compounds such as nitrate, ammonia, acetate, or ethanol. Their mode of nutrition defines the role of fungi in their environment.

Answer:
Proteins in a membrane are C. Both answer choice is true.
Explanation:
Membranes have different types of proteins. <em>Peripheral proteins are the ones that are placed on the inside suface held in place by the cytoskeleton. Integral proteins are the ones that are embedded in the membrane and protrude from either surfaces of the bilayer. </em>These integral proteins also can be carrier proteins, which facilitate passage of molecules through the membrane
; enzymatic proteins, whichcatalyze a specific reaction or they can recognize pathogens, baing cell recognition proteins. In the membrane we can find aquaporins too, which are membrane channel proteins that enable water to cross a membrane.
I don’t know but it might be 4 or 8
Answer:
A natural ecosystem has a diverse amount of species and plants, whereas artificial ecosystems are limited.
Explanation:
Natural ecosystems are self-sustaining and result from spontaneous natural reaction, while artificial ecosystems require the assistance of humans.
