Ecosystems

Biologists measure the number of trophic levels in an ecosystem to understand the flow of energy and nutrients through the food chain. It helps to identify the efficiency of energy transfer between different organisms and how changes in one trophic level can impact the entire ecosystem's stability and biodiversity. Tracking trophic levels also aids in predicting how disturbances or human activities may affect ecosystem dynamics.

Disilting can help in flood control by removing excess sediment buildup in rivers, streams, and drainage channels. This allows for better water flow capacity and reduces the risk of blockages during heavy rainfall, which can help prevent flooding by allowing water to flow more freely and efficiently.

It is important that the team's purpose and role be collaboratively developed for a few reasons. One reason is so that there is no resentment among any members in the group.

This process, called nitrogen fixation, is important because nitrates are an essential nutrient for plants to grow. By converting nitrogen into nitrates, soil bacteria make nitrogen more accessible to plants, enabling them to synthesize proteins and grow effectively. This contributes to the overall health and productivity of ecosystems.

Primary producers in most ocean ecosystems are phytoplankton, which are microscopic algae that use photosynthesis to produce energy. Phytoplankton play a crucial role in marine food chains by converting sunlight into organic matter that fuels the rest of the ecosystem.

A dying tree with holes that animals live in represents a habitat, as it provides a specific environment where these animals can live. The animals living in the tree form a population within this habitat, as they are the same species living in the same area.

Climate has the greatest effect on an ecosystem because it determines temperature, precipitation, and other factors that influence the types of species that can thrive in a particular area. Biotic factors, populations, and communities are all influenced by the climate in an ecosystem.

Sunlight is an abiotic factor found in a rainforest ecosystem. It is essential for photosynthesis, which drives the growth of plants in the ecosystem.

Nepal does not have desert ecosystems or coral reef ecosystems.

The first organisms to colonize and start the process of primary succession are pioneer species such as lichens and mosses. These organisms can grow in harsh conditions and help to break down rock and build up soil, paving the way for other plants to establish themselves.

Bacteria

The three special relationships among organisms in a community are mutualism, where both species benefit from the interaction, commensalism, where one species benefits and the other is neither helped nor harmed, and parasitism, where one species benefits at the expense of the other.

In the eater-eaten relationship, the eater is the one doing the eating, while the eaten is the one being consumed or eaten.

1. Sunlight, rocks, air
2. Trees, water, animals
3. Soil, grass, insects

No, clouds are not living. They are groups of water vapor suspended in the atmosphere.

Examples of primary disturbances include earthquakes, volcanic eruptions, meteorite impacts, and wildfires. These events directly affect the environment by altering landscapes, impacting ecosystems, and disrupting natural processes.

A grub is a consumer. Grubs are immature insect larvae that primarily consume organic matter such as plant roots or decomposing plant material to obtain energy for growth and development.

Competition.

But more to the point it depends on the species.

The Lokta-Volterra equations can be used to produce isoclines that show the expected result but in simpler terms it depends on how well each reproduces and who was there first. Sometimes either species will "win" and force the other out and other times they may find equilibrium where both coexist.

On longer timescales the first species that gets the opportunity will generally evolve into a different niche will often take it and move out of the overlap.

A Eucalypt depends on abiotic factors, such as sunlight, water, carbon dioxide, to make food by photosynthesis. A eucalypt depends on biotic factors such as birds eating insects which were feeding on leaves, and on birds and insects to pollinate flowers

A soft bottom ecosystem is an aquatic environment where the substrate is composed of fine sediments such as sand, mud, or silt. These areas provide habitat for a variety of organisms such as worms, clams, and small fish that burrow or live on the sediment surface. Soft bottom ecosystems are important for nutrient cycling and serve as feeding and nursery grounds for many marine species.

*parasitism is where one animal is helped while other is harmed*

commensalism is where one is helped and other is not really affected

mutualism is where both animals are helped

Disruption of ecosystems can be caused by human activities such as deforestation, pollution, overfishing, and urban development. Climate change is also a major disruptor, leading to shifts in temperature, precipitation patterns, and sea level rise that can negatively impact ecosystems. Invasive species introduced by human activities can outcompete native species and disrupt ecosystem balance.
