Plants make their own food and are called producers. What do plants need to make their own food? A) soil, air and water B) soil,
djyliett [7]

Answer:

D) energy from the sun, air, and water

Explanation:

Plants are producers because they undergo photosynthesis. Photosynthesis is the process of taking sunlight, CO2, and water to produce ATP in the form of glucose and oxygen.

For plants to make their own food they require the reactants of photosynthesis. The reactants are sunlight+6CO_2 + 6H_2O. In other words, sunlight, carbon dioxide (air), and water. Without these reactants, photosynthesis cannot occur.

Things such as soil and fertilizer are helpful to a plant's growth; however, they are not required in the process that creates food for plants.

kotykmax [81]

Answer:

The four-letter word which speaks to the ability of an organism to modify its behavior or actions to external stimuli is <u>Move.</u>

Explanation:

Movement gives organisms the ability to move away from or towards an external stimulus depending on whether it is a detrimental stimulus or a favourable one.

Examples of stimuli are:

  1. Light: All organisms respond to the presence of light. Some stay away from it and remain at sleep until the sun goes down. They are called nocturnal. Others gravitate towards it. Plants always grow towards light.
  2. Temperature: Some organisms favour cold environments, other the temperate parts of the earth
  3. Sound: The sound of a carnivorous animal such as the lion will put a deer to flight. The sound of a mother hen calling out to her chicks will attract them to her.

Cheers
