Which statement best describes the movement of energy and matter in this system?

Which statement best describes the movement of energy and matter in this system?

So, the correct answer is ‘Energy flows while matter is cycled’.

What best describes the movement of energy during photosynthesis?

Which statement best describes the movement of energy during photosynthesis? Sunlight is absorbed by a plant’s leaves and is converted into energy stored in sugars.

Which statement describes the law of conservation of energy?

The law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another.

Which statement accurately describes how matter and energy are used in ecosystems?

Which statement most accurately describes how matter and energy are used in ecosystems? Energy flows through ecosystems; matter cycles within and through ecosystems. The law of conservation of matter states that matter cannot be created, yet matter is sometimes gained or lost to an ecosystem.

Which statement best describes the role of decomposers?

They break down organic compounds into products used by other organisms. Decomposers are the bacteria and fungi responsible for consuming the last organic remains of dead producers and consumers. The function of decomposers is essential, as they convert dead matter into simple inorganic molecules.

What is the concept of energy flow through living organisms?

Energy flow is the flow of energy through living things within an ecosystem. All living organisms can be organized into producers and consumers, and those producers and consumers can further be organized into a food chain. Each of the levels within the food chain is a trophic level.

What is the importance of energy flow?

The energy flow in the ecosystem is important to maintain an ecological balance. The producers synthesise food by the process of photosynthesis. A part of the energy is stored within the plants. The remaining energy is utilised by the plants in their growth and development.

How does energy flow in an ecosystem explain in your own words?

Energy moves life. The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. Our ecosystem is maintained by the cycling energy and nutrients obtained from different external sources. The herbivores at the second trophic level, use the plants as food which gives them energy.

What is the transfer of energy from one organism to another called?

It is this process which determines how energy moves from one organism to another within the system. In a food chain, energy is transferred from one organism to another. The sequential chain of eating and being eaten by other organisms in nature is called ‘food chain’.

How is energy lost from plants?

Energy is lost in several ways as it flows along these pathways of consumption. Most plant tissue is uneaten by herbivores, and this stored energy is therefore lost to the plant-herbivore-carnivore food chain. In terrestrial communities less than 10 percent of plant tissue is actually consumed by herbivores.

How energy moves through an ecosystem?

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

What are three ways to show how energy flows through an ecosystem?

Key Points

  • Food webs illustrate how energy flows through ecosystems, including how efficiently organisms acquire and use it.
  • Autotrophs, producers in food webs, can be photosynthetic or chemosynthetic.
  • Photoautotrophs use light energy to synthesize their own food, while chemoautotrophs use inorganic molecules.

What is the difference between energy flow and biogeochemical cycle in an ecosystem?

Energy flows through an ecosystem and is dissipated as heat, but chemical elements are recycled. The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle.

What is the smallest ecosystem in the world?

The smallest land areas are occupied by tundra and temperate grassland ecosystems, and the largest land area is occupied by tropical forest. The most productive ecosystems are temperate and tropical forests, and the least productive are deserts and tundras.

What is found in an ecosystem?

Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity. Every factor in an ecosystem depends on every other factor, either directly or indirectly.

What did you learn about ecosystems?

Ecosystems are the basis of survival for all living things. We depend on plants and animals for food. In order for us to exist, we need to cultivate and nurture other organisms. We also need to cherish the non-living things within our environment like our air and water so we can continue living as a population.

Why is ecosystem so important?

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.

How does the ecosystem help humans?

Why do ecosystems matter for human health? Ecosystem services are the benefits that people obtain from ecosystems. From the availability of adequate food and water, to disease r
egulation of vectors, pests, and pathogens, human health and well-being depends on these services and conditions from the natural environment.

Are humans important to the ecosystem?

Humans are an integral part of ecosystems. Ecosystems provide a variety of benefits to people, including provisioning, regulating, cultural, and supporting services. Provisioning services are the products people ob- tain from ecosystems, such as food, fuel, fiber, fresh water, and genetic resources.

Why are humans important to the environment?

Humans need to interact with the environment to obtain our food, water, fuel, medicines, building materials and many other things. Advances in science and technology have helped us to exploit the environment for our benefit, but we have also introduced pollution and caused environmental damage.

How are humans impacting the environment?

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
