Because it shows the relation of organisms with each other in a habitat, rather than just a small segment of it like a food chain. It is also still pretty easy to understand like a food chain
It's more beneficial due to the fact you can add more organisms into the mix, and show how they interact with each other in an ecosystem. Rather than just doing a small segment of about 3 or 4 animals in a basic food chain, you can have as many different animals as you want from an ecosystem in a food web, with whom both can eat the same organism, be it a producer or less predator.
You can also begin to identify possible circumstances or effects of the removal or the decrease or increase of one or more species in the ecosystem.
For example, the producer on the diagram could be grass, and sheep and goats are eating it, and mountain lions and wolves eating the sheep and goats. The Humans nearby hunt the mountain lions and kill off the mountain lions.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three stages
Answer: A. It is a recessive trait.
Explanation: In pea plants, seed shape and seed color are controlled by genes located on different chromosomes. Seeds may be round (R) or wrinkled (r), with the allele for round seeds being dominant. The student is asked to predict the offsprings' pea shapes (both round and wrinkled; all round; all wrinkled; or can't predict). Because the allele that produces wrinkled peas is recessive, the offspring of this cross will all have wrinkled peas.
Basic charged atomic particles are electrons (negatively charged) and protons (positively charged). It is a particle on an atomic scale that is charged
