Answer:
1. D. Only DNA contains genetic information
2. D. Nitrogen and Phosphorus
Explanation:
1. Lipids are insoluble in water unlike other molecules. It stores energy within the fat tissues and cushion internal organs against trauma.
Carbohydrates are sugar units such as monosaccharides, disaccharides molecules which makes up starch that is fuel to your cells.
DNA is a type of nucleic acid that contains genetic information which influences your personal characteristics.
2. The family Rhopalodiaceae has the ability to perform nitrogen fixation, which allows diatoms to fix atmospheric nitrogen. And phosphorus has been found in some diatom species in the Black sea region which does not affect its reproduction rate and also helps in carbon cycle.
They have to adapt to the water, the animals in the ocean, the way they hear and see.

Answer:
Decomposers
Explanation:
The diagram in this question illustrates a food web, which is a series of interlinked food chains in an ecosystem. In a food chain as depicted in the image, the arrows point to the organism that feeds on another organism. For example, an arrow is pointing from Idaho fescue to an Elk meaning that the elk will feed on that plant.
Different trophic levels constituting organisms exists in the food web including; producers (plants), primary consumers, secondary consumers, tertiary consumers etc. However, as observed in the image, a general arrow carrying along all the organism is pointing towards the organism in the question mark. This organism is called DECOMPOSER.
A decomposer, usually a microorganism, is an organism that breaks down dead organisms and returns the nutrient to the soil for recycling. All organisms in the food web will eventually die and when they do, they'll be decomposed by a decomposer. This is why the arrow pointing towards the decomposers include all organisms.
