D. Because an amino acid is a monomer of a protein, meaning when a bunch of them are put together it’s a protein. And so it is when a bunch of monosaccharides are put together, it makes a polysaccharide

trace fossil: A type of fossil reflecting the reworking of sediments and hard substrates by organisms including structures like burrows, trails, and impressions.
fossil record: All discovered and undiscovered fossils and their placement in rock formations and sedimentary layers.
strata: Layers of sedimentary rock.

Explanation: hope this is what you mean if not ill try again
The energy-rich compound needed by organism is : Carbohydrates
Carbohydrates consist of the combination of the existing Carbon, Hydrogen, and Oxygen alone.
For human, The source of carbohydrates could be found in almost every food, but the huge amount could be found in rice, potato, corn, cassava, oatmeal, etc

Which abiotic factor most likely controls where the plants live in this environment ?
Oxygen levels for aquatic animals
Oxygen from the air and oxygen produced by aquatic plants dissolves in water. Without this, aquatic animals would suffocate and die. Healthy lakes and rivers have high levels of oxygen, and polluted waters often have low levels of oxygen. This pollution means that only certain species can survive there such as sludgeworms. These are bioindicator species because their presence or absence informs us about the condition of the habitat.
Carbon dioxide levels for plants
Carbon dioxide is a reactant in photosynthesis which means plants need it to survive. Areas with higher levels of carbon dioxide are more likely to have healthy plants growing. Farmers often release carbon dioxide within their greenhouses to maximise their crop yield. Woodlands often have higher carbon dioxide levels than open grassland, so many plants living in open areas have evolved mechanisms to overcome a shortage of carbon dioxide.
