The biological species concept proposed by Mayr states that a biological species is a population whose members can interbreed and produce fertile offspring.
<h3>What is the biological species concept?</h3>
The biological species concept is a model used in biology sciences to delimit a species through mating fertile features of the individual that belong to such species.
This concept (biological species concept) was proposed by Ernst Mayr to understand how each species represent a functional unit.
In conclusion, the biological species concept was proposed by Mayr and states that a biological species is a population whose members can interbreed and produce fertile offspring.

Through my research I found questions similar to this and it appears you forgot to add ''from the external environment and transforming those energies into neural energy'' after stimulus energies, and if that's correct than the answer would be FALSE because that's not true.
The picture it’s not clearly
Answer:
Photosynthesis happens in the leaves of a plant.
This is a chemical reaction, which takes place inside a plant, producing food for the plant to survive. For photosynthesis to take place, carbon dioxide, water and light are needed.

Marine ecosystems cover approximately 71% of the Earth's surface and contain approximately 97% of the planet's water. They generate 32% of the world's net primary production. They are distinguished from freshwater ecosystems by the presence of dissolved compounds, especially salts, in the water. Approximately 85% of the dissolved materials in seawater are sodium and chlorine. Seawater has an average salinity of 35 parts per thousand(ppt) of water. Actual salinity varies among different marine ecosystems.
A classification of marine habitats.
Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live. The benthic zone consists of substrates below water where many invertebrates live. The intertidal zone is the area between high and low tides; in this figure it is termed the littoral zone. Other near-shore (neritic) zones can include estuaries, salt marshes, coral reefs, lagoons and mangrove swamps. In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web.
Classes of organisms found in marine ecosystems include brown algae, dinoflagellates, corals, cephalopods, echinoderms, and sharks. Fishes caught in marine ecosystems are the biggest source of commercial foods obtained from wild populations.
Environmental problems concerning marine ecosystems include unsustainable exploitation of marine resources (for example overfishing of certain species), marine pollution,climate change, and building on coastal areas.
