Can a bagworm bite a person?

Bagworms are caterpillars that construct protective cases made of silk and debris. They do not bite people or animals as they are herbivores. The main concern with bagworms is the damage they can cause to trees and plants by feeding on their leaves.

What are the features of a food chain?

A food chain shows the flow of energy and nutrients from one organism to another in an ecosystem. It consists of producers, consumers, and decomposers. Each level represents a trophic level, with energy being transferred from one level to the next.

What are examples of detritivores?

A detritivore feeds on plant and animal remains and other dead matter collectively called detritus. They recycle decomposing material and return it to the food chain.

Detritivorous animals include:

Diplura, millipedes

Isopoda, woodlice

Collembola, springtails

Mollusca, slugs and snails

Larger specialists are:

Scarabaeidae, dung beetles

Scathophagidae, dung flies

Silphidae, burying beetles

Detrivores also include earthworms, bee-maggots, crabs and vultures.

Are humans at the top of the food chain?

The widely held belief that humans are at the top of the food chain is actually wrong. Humans are nowhere near the top. Ecologists rank species by their diets using a metric called the trophic level. Plants, which produce their own food, are given a rank of 1. Herbivores, which eat only plants, are ranked 2. Pure apex predators (animals that eat only other animals and have no predators of their own, like tigers, crocodiles, boa constrictors, polar bears, and orcas) rank a 5.5.


A team of French researchers used food supply data from the U.N Food and Agricultural Organization (FAO) to calculate the human trophic level (HTL) for every country for which data is available, and their results were published December 2, 2013 in the Proceedings of the Natural Academy of Sciences. They found that based on diet, humans score a 2.21, roughly equal to anchovies and pigs.

Okapi in a food chain?

Okapi are herbivores that feed primarily on leaves, grasses, buds, and fruits. In a food chain, they would occupy the position of a primary consumer, as they consume producers (plants) to obtain energy. They are an important link in the food chain as they provide energy to predators in the ecosystem through their consumption of plants.

What is a Desert food webs?

A desert food web is a representation of the relationships between organisms in a desert ecosystem, illustrating how energy and nutrients are transferred through various species. It typically shows the interconnectedness of producers, consumers, and decomposers in the desert environment. This helps to understand the complex interactions that occur in the desert ecosystem.

What is a giant pandas food chain?

Like any animals Giant Pandas have "typical" food and a "once in while" food. Their diet is over 99% bamboo. Occasionally eat other plants such as grasses, wild tubers. Very rarely they eat meat, birds, rodents if they can catch then but also carrion if they find it..So the principal food chain is "Bamboo -> Panda" Dead pandas ay be eaten by carnivores, rodents or insects.

Eagles food chain?

In an eagle food chain, eagles are apex predators. They primarily feed on small mammals, fish, and occasionally other birds. They play a crucial role in controlling the populations of their prey species, thereby helping maintain the balance of their ecosystem.

Compare and Contrast a food web and a food chain?

A food chain is one animal right after each other (ex. hawk> snake> mouse> grass) and on a food chain things branch off. (ex. hawk and eagle> snake and cat> mouse and cow> grass).

All of this would be in diagram form. Look up pictures of food chain and food web on the internet.

What do all food chains start with?

All food chains start with producers, such as plants or algae, that are able to create their own food through photosynthesis. These producers are the base of the food chain and support all other organisms in the ecosystem.

Is a giraffe at the top or bottom of the food chain?

A giraffe is closer to the top of the food chain as they are herbivores that are preyed upon by few predators such as lions or crocodiles. They primarily feed on leaves from tall trees, giving them relatively few natural predators.

Can leaves that are not green make food?

Yes, leaves do not have to be green to photosynthesize and make food. The green is caused by chlorophyll, the most common and the most efficient, but not the only, compound that can extract energy from sunlight. Other pigments that can photosynthesize include cartenoids and phycobilins, and non-green leaves that photosynthesize range from brown and red seaweeds to red or yellow lichens and purple-leaved plum trees.

What is a complex network of food chains?

When all food chains in a habitat are joined together in some way, they form a food web. They are normally several food chains all joined up together, and may include the same predator or prey more than once in a food chain. Food webs are slightly more complex than food chains, and may sometimes be harder to read and understand. hope this helps

What is the food chain for a sea lion?

sea slugs main food source is a specific type of "alga". the sea slugs make a cut in the alga and sucks its cytoplasm and digest most of it but retains the plastids that trap the solar energy and so on plastids continues to photosynthesize and provide food to slugs.

theree is requirement of certain gene for the process of photosynthesis.... and slugs contain at least one gene required for plastid functioning. Once slug has acquired sufficient amount of plastids it can suvive like plants for atleast nine (9) months by trapping solar energy and converrting it into food with the help of plastids.

so the required food chain for sea slugs is as :

algae (cytoplasm)-=__=------------ -sea slugs

Where is a Meerkat on a food web?

A meerkat is a secondary consumer in a food web, meaning it typically eats primary consumers like insects, small mammals, and birds. It is an important part of the ecosystem as it helps regulate the population of its prey species.

What is the definition of food web?

Dictionary.com defines a food web as "a

series

of

organisms

related

by

predator-prey

and

consumer-resource

interactions;

the

entirety

interrelated

food

chains

in

an

ecological

community."


To put it simpler, a food web is basically two more connected food chains. It shows that cows and horses both eat grass, and wolves eat both of them, and so on.


What is a food web for the Simpson desert?

In the Simpson Desert, the food web includes plant species like spinifex grass and mulga trees that are consumed by herbivores like kangaroos and desert mice. Predators such as snakes and birds of prey then feed on these herbivores, forming a simple food chain within the desert ecosystem.

What animals are at the top of the food chain?

Well for the whole entire world, it's the human. If you are talking about animals. There is lots of different types.

Grizzly Bear

African Lion

Leopard (depends which one really)

Siberian Tiger.

Do you know what? I don't want the answer to be too long so research it yourself.
This is just my opinion. 1. Humans 2. lions or killer whales 3. bald eagle
Humans are at the top of the food chain and are the most cunning/intelligent species on Earth. No natural predators threaten the survival of humans (in other words, no other species competes with the selection of the race). Being at the top also means that it takes a lot more energy to satisfy the needs of energy transfer in the chain.

What is the role of decomposers in a food chain?

Decomposers break down dead organic matter into simpler substances, recycling nutrients back into the environment. They play a crucial role in nutrient cycling within ecosystems by releasing essential minerals and elements that can be utilized by producers in the food chain. Ultimately, decomposers help maintain ecosystem balance and support the overall health of the environment.

What do wolves eat food web or food chain?

A Person! No the first peron is a complete idiot. No healthy wolf would kill a person. They prey on ungulates like deer and moose or other large animals like bison. Smaller predators like lynxes, bobcats, coyotes and foxes (not usually). Or small mammals like hares, squirrels, chimmunks and other rodents. They might prey on the babies of bears and cougars but not adult ones. They may kill them if they want to though, for a good reason.

What food chain does a Kiwi fit into?

Kiwis are omnivores, so they can fit into multiple food chains depending on their diet. They primarily consume fruits, seeds, insects, and sometimes small reptiles or birds. In their ecosystem, they can be both prey and predators, influencing various food chains.

Is a lichen in a arctic tundra food chain a consumer?

Yes, lichens in the arctic tundra food chain are considered primary producers rather than consumers, as they make their own food through photosynthesis using sunlight, water, and nutrients from the soil. They are an important food source for herbivores like caribou and musk oxen in the arctic tundra ecosystem.

What do decomposers do in the food chain?

Decomposers, like bacteria, break down dead animals and plants. Without them, our earth would be a big pile of carcasses. THIS ANSWER CANNOT BE REPRODUCED OR COPIED IN ANY FORM WITHOUT THE PERMISSION OF WIKI ANSWERS USER SEALPUP11.

What do you do if you get pepper in your proboscis?

If pepper gets into your proboscis (nose), try to blow your nose gently to remove it. If the irritation persists, rinse your nasal passages with saline solution to flush it out. Avoid sniffing forcefully, as this can push the pepper farther in.

Whelks fit in food chain?

Whelks are typically carnivores that feed on small mollusks, crustaceans, and other invertebrates. They are preyed upon by larger predators such as fish, crabs, and sea otters. Whelks play a role as both predator and prey in the marine food chain, helping to maintain the balance of the ecosystem.
