Food Chains and Food Webs

the food web will stop working. The snake needs the mouse to get it's energy and then the Eagle gets it's energy from the snake. But if there was no mouse the snake will have nothing to eat and will die if the snake dies then there is no way the Eagle is gonna get it's energy.

An Io Moth can scare away birds by flashing its bright eye spots located on its hindwings when threatened. The sudden appearance of these eye spots can startle or confuse predators, giving the moth a chance to escape.

Pangolins are insect-eating mammals, so they are primarily consumers in the food chain. They are known to eat ants and termites, which places them at a lower trophic level in the food chain. However, they can also become prey for larger predators, such as big cats and humans, which then places them higher up in the food chain.

The gulper eel's food chain typically consists of smaller fish, crustaceans, and cephalopods as their primary food sources. They use their large jaws and expandable mouth to consume prey items found in the deep-sea environment where they live. In turn, gulper eels may also serve as prey for larger deep-sea predators such as sharks and other large fish.

A food web can be thrown out of balance by human activities such as overfishing, habitat destruction, pollution, and introduction of invasive species. These activities can disrupt the natural interactions between different species in the food web, leading to population declines or extinctions that can have cascading effects on the entire ecosystem.

If herbivores were to die off, it would lead to a disruption in the food chain. Their absence would lead to a decrease in prey for carnivores, which could potentially result in a decline in carnivore populations. This imbalance could also affect plant populations as herbivores play a role in shaping plant communities through grazing.

It is called a quaternary consumer. Fifth is quinary.

If coyotes disappeared from the deserts there would be less predation on rodents, rabbits and hares so these populations would soar putting stress on the limited vegetation available for food. Rodents and such also carry a number of diseases that can be transmitted to humans and such transmissions would be more common with higher populations and no coyotes for control and these animals moved into human populated areas searching for food and water.

If a link in a food chain is broken, it can disrupt the entire ecosystem. For example, if a predator species goes extinct, it can lead to overpopulation of its prey species, which can then have cascading effects on other species lower in the food chain. This can lead to imbalances in population sizes, changes in species composition, and overall ecosystem instability.

A food web represents an ecosystem better than a food chain because it shows a more complex network of interconnected food relationships among different organisms in an ecosystem. A food web illustrates various feeding interactions and energy flow pathways, capturing the complexity of interactions and the role of multiple species in maintaining balance within the ecosystem.

Non-living things in the food chain, also known as abiotic factors, include sunlight, water, temperature, and nutrients in the soil. These elements provide the foundation for the food chain by supporting the growth and survival of plants, which are then consumed by other organisms in the ecosystem.

Ecosystems with many connected food chains are known as complex or diverse ecosystems. These ecosystems have a variety of species interacting with each other in intricate ways, resulting in multiple food chains and a high level of biodiversity. Examples include tropical rainforests and coral reefs.

Ball-like bacteria linked in chains are called streptococci.

A consumer that follows a producer in a food chain is known as a primary consumer or herbivore. These organisms feed directly on producers (plants) for energy and nutrients, forming the second trophic level in the food chain. Examples include rabbits, deer, and cows.

Button quails are omnivores that primarily feed on insects, seeds, and vegetation. In their food web, they may be preyed upon by larger birds of prey, snakes, and mammals. They are also important in controlling insect populations, serving as both predator and prey in their ecosystem.

I thought some living things are not organisms, because they are not free living.

In a food web, matter cycles through different organisms as they consume and decompose each other. Energy, on the other hand, flows in one direction through the food web as it is transferred from one organism to another through feeding.

Food webs specifically show the flow of energy and nutrients through an ecosystem via feeding relationships, while interaction webs include other types of relationships such as competition, predation, and mutualism. Interaction webs provide a more comprehensive view of the complex interactions within an ecosystem beyond just who eats whom.

Primary production is the production of organic compounds from atmospheric or aquatic carbon dioxide. It may occur through the process of photosynthesis, using light as a source of energy, or chemosynthesis, using the oxidation or reduction of chemical compounds as a source of energy. Almost all life on earth is directly or indirectly reliant on primary production. The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae are primarily responsible. Primary production is distinguished as either net or gross, the former accounting for losses to processes such as cellular respiration, the latter not.

Leeches are typically considered consumers in the food chain, as they feed on the blood of other organisms. They play a role as decomposers in aquatic ecosystems, breaking down organic matter and recycling nutrients.

African penguins primarily feed on fish such as anchovies and sardines. They are also preyed upon by larger predators like sharks and seals. As secondary consumers, they play a vital role in the marine food chain by controlling fish populations.

You eat at the lowest trophic level, which would be grains and grasses. As you progress up the food chain, energy isn't lost but transferred into another form, heat.

Remember the first law of Thermodynamics? The first law of thermodynamics states that Energy is Conserved and that under normal conditions is neither created nor destroyed, but transferred or transformed.

When you eat low on the trophic level (Lowest-highest.....1. grains and grasses ( Primary producers), 2. Herbivores (animals that eat plants, Primary consumers) 3. Omnivores (eat plants and animals, secondary consumers) and 4. Carnivores (eat animals, tertiary or TOP consumers). Humans are carnivores.

Second law of thermodynamics states that the ecosystems are not 100% efficient and with each successive energy transformation as grain is passed to the herbivores, energy is transformed into heat and escapes the herbivores, so when the omnivores eat the herbivores there is less energy stored inside the herbivores and so on all the way to the top of the trophic level, less energy is available to do work because each transfer or transformation leaves less energy behind, even though it is not lost.

The second law of thermodynamics states that we could feed more people if we consumed grain rather than feeding it to livestock, then eating the livestock.

If you would like to eat so that you would be consuming the most amount of energy per meal, you eat primary producers. Eating low on the trophic level is not just a good way to eat where energy is most plentiful in our food but it is also good for nature, the earth and a variety of other reasons.

I wish you the best of luck if you plan to become a vegetarian, it is a very healthy lifestyle, but you do need to be educated so that you are getting the proper amount of nutrients and protein, which are in abundant quantities in grains and grasses ( I don't mean grass as the kind on your lawn either) Look up what types of foods are considered grasses, you'd be surprised.

****Also, Do Not Forget that there IS NO loss of energy as you move higher up the food chain, only a transformation of energy, which means that there is less energy available to do work. Just like the laws of matter, so too is the 1st law of thermodynamics. Both laws state that under normal conditions matter or energy cannot be created or destroyed, but can be transformed or transferred.

These are fundamental rules of science so that is why I am really stressing the point of energy not being lost.

If you have any questions, please feel free to ask me.

say you had three animals:

chicken, fox, and tiger.

(yes tiger can eat the chicken but stay with me here) if the fox were to become extinct. and no other animals could take its place, you could:

A: find a forien animal and bring it over to the area (AKA bioinvasion) it would work f it would eat chickens and if the tiger could eat it.

B: Genetic modification. you could find fox DNA in any remains of the fox, including the waste the tiger produces. with that you can create a fox. to link the chain.

If 2 producers disappeared from a food web, it would disrupt the entire ecosystem. Producers are at the base of the food chain, so their absence would affect the consumers that rely on them for food. This could lead to a decline in population for consumers and subsequent disruptions up the food chain.
