Food chains and food webs represent the feeding relationships in ecosystems. They show who eats whom. Therefore, they model the flow of energy and materials through ecosystems.

Food chains and food webs model feeding relationships in ecosystems. They show how energy and materials are transferred between trophic level when consumers eat producers or other organisms. A food web is a diagram of feeding relationships that includes multiple intersecting food chains.

Feeding relationships show what organisms eat or are eaten by others and through this the levels of organisation in an ecosystem. These can be shown in food chains , which add together to make food webs for a habitat .

There are three different types of symbiotic relationships: mutualism, commensalism, and parasitism.

There are four main types of symbiotic relationships: mutualism, commensalism, parasitism and competition.

What are the three main types of feeding relationships?

• Mutualism: both partners benefit.
• Commensalism: only one species benefits while the other is neither helped nor harmed.
• Parasitism: One organism (the parasite) gains, while the other (the host) suffers.

Herbivore: Eats only plants. Carnivore: Eats only meat. Omnivore: Eats both plants and meat.

There are three major types of community relationships: symbiosis, predation, and competition.

The interaction among organisms within or between overlapping niches can be characterized into five types of relationships: competition, predation, commensalism, mutualism and parasitism.

Food web is an important ecological concept. Basically, food web represents feeding relationships within a community (Smith and Smith 2009). In a detrital food chain, dead organic matter of plants and animals is broken down by decomposers, e.g., bacteria and fungi, and moves to detritivores and then carnivores.

Energy Flow in Ecosystems. In every ecosystem, organisms are linked through feeding relationships. There are a great many feeding relationships in any ecosystem, but energy always flows from primary producers to various consumers. A food chain is a sequence in which organisms transfer energy by eating and being eaten.

Food chains and food webs are diagrams that represent the feeding relationships from producers to consumers to decomposers. They show who eats whom. In this way, they model how energy and matter move through ecosystems. A food chain represents a single pathway through which energy and matter flow through an ecosystem.

A good relationship with food involves welcoming all foods in moderation, eating foods that you enjoy, not allowing food to control your life, and knowing that the foods you eat do not define your value as a person.

Vital to the interdependence of life in estuaries is the feeding relationship, known as the food web. larger plants such as mangroves, saltmarsh and seagrass, which also produce food through photosynthesis and absorb nutrients form the water. zooplankton – microscopic animals that eat phytoplankton.

Energy flows through an ecosystem in only one direction. Energy is passed from organisms at one trophic level or energy level to organisms in the next trophic level. Producers are always the first trophic level, herbivores the second, the carnivores that eat herbivores the third, and so on.

Common animals include: shore and sea birds, fish, crabs, lobsters, clams, and other shellfish, marine worms, raccoons, opossums, skunks and lots of reptiles.

Estuaries

1. Conserve water in your daily life.
2. Dispose of household and yard chemicals properly; follow disposal directions on their labels.
3. Don’t be wasteful: reduce, re-use and recycle every day.
4. Pick up trash; participate in trash clean-up days.

5 living and non living things found in estuaries

• Fish.
• Shellfish.
• Migratory Birds.
• Oysters.
• Mud Crabs. Fish, shellfish, and migratory birds are just a few of the animals that can live in an estuary.
• Its water/body of warer.
• Its land around it.
• stones and rocks.

Poor water quality affects most estuarine organisms, including commercially important fish and shellfish. The pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

Challenges for organisms Two major problems for organisms living in an estuary are fluctuations in salt concentration and sedimentation. Salt concentrations are regulated by an organism, and when the concentration in the water fluctuates, it becomes harder to adjust.

A. In an estuarine ecosystem these factors are light, oxygen, water, nutrients, temperature, salinity, and space.

A Clean Environment Is Essential for Healthy Living: The more you don’t care about our environment, the more it will become polluted with contaminants and toxins that have a harmful impact on our health. Air pollution can cause respiratory diseases and cancer, among other problems and diseases.

Try eliminating the amount of meat, fish or dairy you eat each day. Doing this will help to cut greenhouse gas emissions and reduce energy consumption. According to an Independent article, you could reduce your “carbon footprint from food by up to 73 percent” just by incorporating a vegan diet!

Answer: Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilisation and sustain our economies.

Respect the environment, making rational use of natural resources and taking steps to prevent pollution from the different processes involved in our industrial operations. Promote the sustainable use of raw materials and natural resources.

Human activity is a major cause of air pollution, especially in large cities. Human air pollution is caused by things such as factories, power plants, cars, airplanes, chemicals, fumes from spray cans, and methane gas from landfills. One of the ways that humans cause the most air pollution is by burning fossil fuels.

Since 1970, the Environmental Protection Agency (EPA) has been working to protect the nation’s natural resources. We do not work alone. EPA has partnerships with state and local governments, other federal agencies, environmental groups, businesses and industries, and growing legions of concerned citizens.

Two-thirds of Democrats and independents say the environment is the responsibility of the government, while a majority, 57 percent, of Republicans consider it an obligation of individuals.

Fossil fuel firms clearly play a major role in the climate problem. A major report released in 2017 attributed 70% of the world’s greenhouse gas emissions over the previous two decades to just 100 fossil fuel producers. An update last year outlined the top 20 fossil fuel firms behind a third of emissions.
