Explanation:
Capillary action pulls water into the root of a tree while the forces of cohesion and adhesion continually move the water up the tall tree.
Water is a polar molecule. Strong hydrogen bonds hold the water molecules together. This is a kind of dipole - dipole interaction and it accounts for the cohesive forces in water.
The forces of adhesion bind water to other surfaces. In the case of plants, the adhesive forces facilitates the interaction of water with the xylem cells.
Water enters into the roots of plants by capillary action. Capillary action alone is insufficient to move the water up the tree.
Hence, the forces of adhesion and cohesion, acting together can help water molecules to move up the top of a tall tree.

Answer: Option D
Explanation: this depends on the food source and energy they utilize
Autotrophs are organisms that obtain their food source and energy by synthesizing these themselves using raw materials and energy (energy from the sun) they do this in the process known as photosynthesis obtaining energy from sunlight and they are also classified as autotrphs due to the presence of some components/features that will enable them to be able to synthesize their food for example, plants are autotrophs and they possess chloroplants: an organelle that contains chlorophyll that helps to channel the energy of sunlight into chemical energy and as well also gives plant their characteristic green color. They are also known as producers
Heterotrophs are organisms that rely on producers or other heterotrophs to obtain their food and energy. They either depends directly or indirectly on the producers for their energy source i.e. herbivores egg goats that feed directly on plants like grass; carnivores e.g lion that feeds on the herbivores this depending indirectly on plants.
