Energy:

Solar energy is collected by autotrophs. Energy transformations are never completely efficient as energy is lost as heat and waste and only around 5-20% of energy is passed on to the next trophic level.

Nutrients:
Organisms take in nutrients from their food and these nutrients occur as complex organic molecules in living things. After these organisms died, saprotrophs and decomposers break down these organic molecules into simpler substances. These substances are then recycled when they are absorbed by plants to recreate complex organic molecules.

How are the movement of energy and the movement of chemicals in ecosystem different?

Energy is not recycled, it flows in and out in a unidirection. Chemical energy enters as light energy and is produced by producers and leaves the ecosystem as heat.


How is movement of matter and energy through an ecosystem different?

An example of the transfer of energy is the food chain. This is different from movement of basic elements in the ecosystem because energy gets used, not just moved.


How does matter cycle through an ecosystem and impact its overall functioning?

Matter cycles through an ecosystem as it is continuously recycled and reused by living organisms. This process involves the movement of nutrients and energy through different components of the ecosystem, such as plants, animals, and decomposers. The impact of this cycling is crucial for the overall functioning of the ecosystem, as it helps maintain the balance of nutrients, energy flow, and biodiversity. disruptions in the matter cycle can lead to imbalances and affect the health and stability of the ecosystem.


What are the dynamics of any ecosystem?

two major process 1 = cycling of nutrient 2= chemical energy (food)


How is the movement of energy and nutrients different?

The movement of energy is one-way, flowing through ecosystems from producers to consumers and decomposers. Nutrients, on the other hand, cycle through ecosystems as they are taken up by plants, consumed by animals, and then returned to the environment through decomposition. Energy is lost as heat at each trophic level, while nutrients are recycled within the ecosystem.


What is the typical movement of energy through an ecosystem?

Energy enters an ecosystem through sunlight and is converted into chemical energy by producers through photosynthesis. This energy is then transferred to consumers through the food chain as they eat other organisms. Ultimately, energy is lost as heat as it moves through the ecosystem.


How does the movement of energy differ from the movement of nutrients in an ecosystem?

Energy flows through an ecosystem in a one-way direction, entering as sunlight and being transferred through trophic levels before eventually being lost as heat. Nutrients, on the other hand, cycle within an ecosystem as they are taken up by organisms, released back into the environment through decomposition, and then made available for uptake again by other organisms.


What are the different between energy flow and nutrient cycle?

Energy flow refers to the movement of energy through an ecosystem, typically in the form of sunlight being converted to chemical energy through photosynthesis and then transferred through food chains. Nutrient cycles, on the other hand, involve the recycling of essential nutrients like carbon, nitrogen, and phosphorus through biotic and abiotic components of an ecosystem. While energy flow is unidirectional and constantly requires an input of energy, nutrient cycles are cyclic and involve the uptake, utilization, and release of nutrients by organisms within an ecosystem.


Which is termed as stagnant ecosystem?

A stagnant ecosystem refers to an ecosystem that lacks movement or change, often characterized by a lack of diversity, low productivity, and limited or no movement of energy and nutrients. Stagnant ecosystems typically have low levels of oxygen, causing a decrease in biodiversity and overall ecosystem health. Examples of stagnant ecosystems can include stagnant ponds or lakes with low water flow or oxygen levels.


Why is the movement of basic element in ecosystem different from the transfer of energy?

no thank you for the "beep you" part!! like what the heck!!!

How do chemicals move through an ecosystem?

Chemical nutrients can move through an ecosystem through plants. The plants can extract chemical nutrients from the ground and when animals eat green plants, they transfer from plants to animals.
