Food Chains and Food Webs

Because bigger animals eat those animals at the bottom, then bigger ones eat the ones who ate the ones at the bottom, then those get eaten, and it usually continues until the largest ones at the top of the food chain remain and depend on the ones below them in the food chain to live and then they eat them.

In other words, the ones at the bottom will be relied on and eaten by bigger animals.

ladybugs, among other insects, eat aphids.

well, it could go into both. A food chain is just a simpler version of a food web. A food chain shows just about everything in a particular ecosystem and conects it al. A duck eats stuff and is eaten by other organisms so it would go around the 3rd level of a food chain.

Predators EAT their prey. If the number of prey diminishes there is less food available for the predators to catch so some of them starve to death. Similarly if there are numerous prey then the predators eat well and breed successfully and their numbers go up.

There is therefore a balance between the numbers of predators and their prey.

No, a tick is an animal parasite.

Cellular respiration is the process in which organisms transfer energy from food into ATP.

According to my biology text book a producer is defined as: an organism that uses energy from light (or inorganic chemicals) to convert carbon dioxide to organic compounds. They are the first tropic level because they are able to make their own food through photosynthesis, meaning they do not depend on others for food; all other organisms in the community depend on them for food, either directly (an animal eating them) or indirectly (by eating an organism that ate a producer).

Most sea otters live in the kelp forest ecosystem. Kelp and other algae species are the primary producers of this ecosystem. Sea otters eat sea urchins, abalone, other shellfish, snails, and occasionally other animals unique to a particular area. Just about all of these animals are primary consumers, meaning they eat kelp and algae (some of them are also filter feeders that filter phytoplankton out of the water). Sharks will occasionally eat sea otters, but generally only if the otters are already injured (otherwise they are pretty good at escaping). It is suspected that orcas have recently been eating Alaskan sea otters. Sea otters are a keystone species in their ecosystem, as they keep shellfish and sea urchin populations in check. Without otters, these animals tend to overpopulate and eat all of the kelp. Since everything in the kelp forest (including many kinds of fish) depends on the kelp for survival, this leads to a collapse of the entire food web. The resulting ecosystem is called an "urchin barrens," since it is generally populated almost exclusively by sea urchins and other shellfish.

Bears have very little predators besides humans and the occassional pack of wolves that stumble upon an ill or dying bear. This means that the only groups affected are their prey and other predators of their prey. This may cause a slight disturbance in the food web however, this difference will decrease as time goes by. The fact that there will be more of the bears' prey around and the fact that there will be more food for other predators of their prey will even things out over time.

yes they eat almost anything a nd nothing eats it.

Omnivores eat BOTH plants and animals in a food chain.

There are a lot of animals that will eat snakes other than owls. Almost any raptor (hawk, falcon, eagle, etc.) will eat a snake. There are a number of other mammals that will, as well, such as skunks, badgers, raccoons, weasels, and many more. Predatory wading birds like herons will also eat snakes - even other snakes will eat snakes! Really, just about any predatory animal that is large enough can eat a snake.

It becomes more concentrated as it accumulates higher up the food chain, predatory species eating herbivorous species end up with deposits in their tissues of dangerously toxic levels. Fish are a prime example, as humans routinely eat predatory fish species (tuna, mackerel, cod, salmon, etc.) which have absorbed the DDT and PCBs (and heavy metals like mercury) accumulated in the bait species they feed on. The long life span of these species means over time the levels become dangerous. Fish in many places are now considered dangerous to eat regularly (e.g. salmon from Lake Michigan).

the predator

no

A pond and its characteristics is a 'habitat'

I dont know thats why i asked!

If something like a mouse gets poisoned and dies and somethings eats it that species will get poisoned and killed and son until all species are infected.i forgot

Because when you eat you get energy and a food chain tells you which animal eats what
