what is the key difference between energy and matter in ecological systems?

There are no 'similarities' or 'differences' they are just two different things going on at once simultaneously and cannot happen without each other. You can only say that the difference is that energy cannot be created or destroyed just changes its form and flows. The energy is flowing while the matter is cycling.

The law of conservation of energy states that the total amount of energy in a system remains constant (is conserved), although energy within the system can be changed from one form to another or transferred from one object to another. Energy cannot be created or destroyed, but it can be transformed.

The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.

There are three types of systems in thermodynamics: open, closed, and isolated. An open system can exchange both energy and matter with its surroundings. ... A closed system, on the other hand, can exchange only energy with its surroundings, not matter.

Matter is any substance that has mass and takes up space by having volume. ... Material is a broad term for pure chemical substances or mixture of substances. The physical and chemical properties of materials are studied in materials science. Eg.

As nouns the difference between biosphere and ecosphere is that biosphere is the part of the earth and its atmosphere capable of supporting life while ecosphere is the portion of the atmosphere from sea-level to about 4000 meters in which it is possible to breathe without technological assistance.

Non-living matter There are two types of ecosystems, closed and open. Closed ecosystems are ones that do not have any inputs (exchanges of energy from the surrounding environment) or outputs (exchanges of energy from within the ecosystem). Open ecosystems are ones that have both inputs and outputs.

An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source – this is usually the sun. Plants need sunlight to photosynthesise and produce glucose, providing an energy source for other organisms.

Matter is the Stuff Around You Matter is everything around you. Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume).

Key points. Ecology is the study of how organisms interact with one another and with their physical environment. The distribution and abundance of organisms on Earth is shaped by both biotic, living-organism-related, and abiotic, nonliving or physical, factors.

As nouns the difference between matter and particle is that matter is substance, material while particle is a very small piece of matter, a fragment; especially, the smallest possible part of something.

The difference between heat and thermal energy is that thermal energy is not in the process of being transferred; it is not in transit, but remains as part of the internal energy of the system; heat, on the other hand, is energy in transit, i.e. energy in the process of being transferred from a hotter system.

Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form to another. Power is the rate at which energy is transferred.

Both: They both invlove changes in the state of matter. They both have energy changes. There are new things made either way, no matter if the chemical composition is changed or not.

Everything in the Universe is made up of matter and energy. Matter is anything that has mass and occupies space. ... Energy is the ability to cause change or do work. Some forms of energy include light, heat, chemical, nuclear, electrical energy and mechanical energy.

Differences: in natural ecosystems, recycling of minerals previously used by organisms is the most important source of nutrition, while in agroecosystems exogenous minerals are added, sometimes in large amounts, to compensate for that which leaves the ecosystem as the harvested crop.

Molecules are transported through living organisms, broken down and converted into other molecules as part of growth and biomass allocation. Energy is transferred as matter is transformed from one chemical to another. Matter is oxidized to carbon dioxide and water during respiration.
