Detailed explanation-1: -Which best explains the role of bacteria in an ecosystem? They break down organic matter into necessary nutrient components.
Detailed explanation-2: -What best describes the role of bacteria in an ecosystem? Bacteria break down organic debris to recycle nutrients in the ecosystem.
Detailed explanation-3: -Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
Detailed explanation-4: -At the base of almost every food chain is a producer . These are plants or algae, which photosynthesise . This means they convert energy from the sun into glucose during photosynthesis, which produces biomass . It is this which feeds the rest of the food chain.
Detailed explanation-5: -Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.
