Grass is an autotroph because it obtains the energy it needs from the process of photosynthesis and does not have to consume other organisms for energy.

These agave cacti are examples of a C4 plant, because there are 4 carbon molecules present in C4 plants, as opposed to C3 plants, which contain 3 carbon molecules. C4 plants allow soil moisture to be conserved, which helps them to grow longer in arid environments, such as deserts.

The cuticle layer is the waxy, outer-most layer of the plant. The primary function of the cuticle layer is to prevent water loss in the leaf, and to protect it.

The flower is located underneath the petals, and it is a part of the female reproductive organ of the flower.

This is my puppy Cookie, and she is a heterotroph because she can not produce her own food. Heterotrophs must eat other organisms because they can not create their own food from photosynthesis.
