What type of habitat do dogs and snakes live in? For example, explain if they live in an aquatic or terrestrial ecosystem and describe the abiotic components of its habitat and the zones it lives in. Describe the niche dogs and snakes take within their environment (i.e., trophic level).

Quick answer:

Dogs and snakes both live in terrestrial ecosystems. In terms of abiotic factors, dogs can live in habitats with wider ranges of temperature, because they are endothermic. Dogs and snakes are at similar trophic levels, but their consumer levels will depend on the exact food chain of their environment. Wolves, a type of dog, are apex predators.

This question is asking several questions about two different species. I assume that "dogs" refers to wild dogs, like coyotes, wolves, or foxes. While both dogs and snakes are certainly found in a variety of ecosystems, dogs are capable of surviving in a far greater number and variety of ecosystems than snakes. A main reason for this is that dogs are endothermic and snakes are ectothermic. Snakes depend on the climate to maintain optimal body temperatures, and they are forced to seek refuge during the cold winter months. Any location where the ground stays frozen all year will not be habitable for snakes. For snakes, the temperature is a very important abiotic factor.

Abiotic factors are limiting factors that are not living factors. Temperature, water pH, wind, soil composition, precipitation amounts, and air quality are all examples of abiotic limiting factors. Most species can tolerate a range for certain abiotic factors. Dogs can withstand a greater temperature range than snakes, so they can be found in almost any terrestrial ecosystem in the world occupying different trophic levels of a given food chain.

Both snakes and dogs exist at about the same trophic level within their ecoystems. The base of the trophic pyramid will be producers, followed by primary consumers that eat the producers. Both dogs and snakes survive by eating other consumers, so they would be secondary consumers at the lowest end of the pyramid; however, a wolf is an apex predator. It quite possibly could be a quaternary (or later) consumer depending on the exact food chain.
