An ecosystem is a community of living organisms joined with the non-living components of their environment interacting as a system. Mangroves, Rocky Shores and Sand Dunes may be seen as three independent parts of the ecosystem but if one is disturbed then it affects the other parts of the cycle. There are many examples of ecosystems such as a pond, forest, an estuary, grassland and many more. Hastings Point is an estuary that is continuously threatened by development.…
The nitrogen cycle has a main component which begins with the nitrogen that is in the air. The nutrients that it provides the soil goes through a complex system that is similar to constant recycling. Nitrogen in the air turns into biological matter through bacteria and algae (this is also known as nitrogen fixation). Bacteria in the air mix with nitrogen and it eventually becomes…
Ecosystems: Every living thing interacts with each other and its environment. They do not live along but in communities with like organisms made up of different things, including nonliving…
Ecosystem: all the organisms in a given area as well as the abiotic factors with which they interact a community and its physical environment…
A: An ecosystem is a natural unit consisting of all plants, animals and micro-organisms in an area functioning together with all the non-living physical factors of the environment.…
In an ecosystem, all the component are characterised as biotic, for example animals and plants, or abiotic for example climate, pH, soil characteristics or drainage. These biotic and abiotic factors determine the changes to the vegetation in the ecosystem overtime as they have a great effect on it, such as flooding and animal grazing. Within the ecosystem, there are inputs, outputs, stores and flows which transfer minerals, nutrients, water and light energy. The most important input is light energy from the sun, which is the source of any food chain. Producers start a food chain, but they would not be able to do so without the 2% of energy provided…
Autotrophs get energy to make food through the sun, and the heterotrophs get their energy from consuming the autotrophs; they are indirectly getting their energy from the sun, because that is how the autotrophs grew. With every level, 90 percent of energy is lost.…
• Ecosystem- A particular location on Earth distinguished by its mix of interacting biotic and abiotic components.…
A system formed by the interaction of a community of organisms with their physical environment.…
Energy flows through the ecosystem throughout the sun. The sunlight provides energy for the producers, which then converts the energy into food or nutrients. Producers uses energy to make food. Shortly after consumers will eat the producers, along with other consumers within the ecosystem. Once the producers and the consumers die they are decomposed. Which is recycled back again. Producers are plants while consumers are living. Meaning, primary are herbivores and secondary are omnivores.…
Nutrients are important for organisms to function. Each nutrient has a role in global biogeochemical cycles. A nutrient is a chemical that organisms need to live and grow and are substances an organism's uses for metabolism which must be taken in from its environment that enrich the organism. Two types of nutrients are macronutrients and micronutrients. Macronutrients are needed in large quantities while micronutrients are needed in smaller quantities. A biogeochemical cycle moves chemical element between living, and nonliving parts in the environment. I will describe the water cycle, explaining the major processed involved and the relationship of micronutrients.…
Introduce this section with the food chain discussion card called ‘Under the sea’. Food chains are a flow of energy Food webs exist in a delicate balance. If one animal’s source of food disappears, perhaps from a natural cause such as a drought or a killer disease, many other animals in the food chain are affected. Some populations may decline, and some explode.…
The branch of science that deals with how living things, including humans, are related to their surroundings is called ecology . The Earth supports some 5 million species of plants, animals, and microorganisms. These interact and influence their surroundings, forming a vast network of interrelated environmental systems called ecosystems. The arctic tundra is an ecosystem and so is a Brazilian rain forest. The islands of Hawaii are a relatively isolated ecosystem. If left undisturbed, natural environmental systems tend to achieve balance or stability among the various species of plants and animals. Complex ecosystems are able to compensate for changes caused by weather or intrusions from migrating animals and are therefore usually said to be more stable than simple ecosystems. A field of corn has only one dominant species, the corn plant, and is a very simple ecosystem. It is easily destroyed by drought, insects, disease, or overuse. A forest may remain relatively unchanged by weather that would destroy a nearby field of corn, because the forest is characterized by greater diversity of plants and animals. Its complexity gives it stability.…
13. It is a component of the ecosystem pertaining to the community of living organisms and the aspects of the environment pertaining directly to them. Biotic.…
Air, water, and land—those are the systems. On land, nature moves full circle. Living things are nourished there, grow old and die, then decompose to enrich the land again. A thin envelope of air surrounds the planet. We use its oxygen, exhaling carbon dioxide, which vegetation absorbs. Plants use the carbon for growth by the marvelous process called photosynthesis, and return oxygen to the atmosphere. Thus nature's delicate balance is maintained.…
