Food Chains and Food Webs

predators and prey do depend on each other in that the predators rely on prey for food and they keep population of prey in check which if they did not there would be over population and food for prey would be decreased and they could die from lack of food.

The amount of usable energy ("food") stored in the biomass of organisms is decreased because most of the energy taken in by consumers is used for movement or released as body heat. The percentage passed on is usually taken as 10%, although this is a very generalized average, and different ecosystems have varying efficiencies.

Humans (due to habitat loss or the poisoning of rabbits, squirrels or mice), Lynxes, Mountain lions (Pumas, Cougars), Wolves, Foxes, Coyotes, Eagles, Hawks, Ospreys, Owls, Wolverines, and Badgers present a clear danger to the Bobcat's survival.

i can tell that you are trying to cheat... that's not even a question

your mean..its not cheating on the pretest hahahahaha

hawk; snake; frog; plant

have a wonderful day!!

The white shark is an apex predator (on top of the food chain) and as such, has very few predators. Killer whales and larger sharks pose the only natural threat to an adult white shark.

yes

When one organism gets eaten, the other animal that ate it only gets ten percent of the energy passed on to it. So say a bug eats 10,000 calories worth of grass. Only 1,000 calories get passed on to the bug. When a mouse eats the bug, the mouse gets only 100 calories from the bug. When a hawk eats the mouse, the hawk gets only 10 of the original calories that came from the grass.
More efficient use is made of food plants by humans consuming them directly rather than than first converting them into animal products,since this cuts out at least one of the energy-losing stages in the food chain

They usually eat other plankton, by rapidly ingesting other plankton who are smaller than themselves. Herbivorous plankton ingest (with their mouth) individual alga particles and other types of algae-like small plantasiac creatures.

The bottom of the food web, usually bacteria or fungi. The break down dead organic matter.

Its because that the chlorophyll are hidden under the coloured pigments.And chlorophyll can make food like the green leaves,the "green"that we are refering are because of the chloropyll.

An acorn is the fruit of the oak tree, an oval nut growing in a woody cup.

Well it depends on the environment. If it's a desert it's animals like bilby's and ant lions. Because they eat the bugs/insects/plants of the environment. (First consumers)

If an animal were to be removed from a food chain, the entire ecosystem could easily fall apart or futhermore be destroyed. Say that a herbivore such as a mouse that feeds on grass was too be removed. And that the mouse would be eaten by a snake..the snake population would decrease from starvation and the grass would increase.

Food webs on land and in the water are the same because they both have producers, consumers and decomposers.

It means that it is either an apex predator (if it is a carnivore), or it is simply an animal that is too difficult or dangerous to kill, so no other animal threatens it. For example, the elephant is at the top of the African food chain, mostly because it is the strongest, and no animal hunts it regularly.

They are called "predators."

They may be carnivores (eating meat) or omnivores (eating both plants and animals). The term carnivores includes scavengers, who do not kill their own prey but consume remnants from the prey of other animals. Some animals that are scavengers (coyotes, crows, vultures) are also predators or can become predatory.

No, a fish is a consumer.

because human doesn't produce his own food

Due to the evolution theory bees play a large role in food chains. As they constantly produce Honey (sperm) for their mates. The bears then eat the honey and produce zoo animals for us humans to look.

Bees apart from making honey wich is used for their own and for human consumption also polinate the flowers that they visit thereby ensuring a better harvest of that particular plant. all fruits need polination from bees or other insects to bear healthy fruits.

Arthropod larvae are the quasi-clear tiny white bugs that live inside raspberries (Rubus spp). The larval stage looks like the caterpillar stage of such lepidopterans as butterflies and moths. It may be of different colors depending upon the genus even though one of the most common larvae meeting the above-mentioned description will be those of the raspberry beetle (Byturus unicolor).

Humans are very powerfull and can kill anything on earth

Without are technology we would be low in the foid chain and tigers & lions &sharks would over rule us

Secondary consumer because it does not eat plants but a grasshopper is

Crocodiles are at the top of the food chain. They have few natural enemies, although birds of prey and monitor lizards, even bigger crocs eat the young. Adults are sometimes killed by big cats, and there exists video of a tiger killing a large mugger croc in India. Humans also kill many crocodiles.
