This is a picture of green grass. The grass is an example of an autotroph. An autotroph uses different resources like sunlight, water, and carbon dioxide to make their own food and energy. Grass is photosynthetic, which makes it an autotroph because photosynthetic organisms self-feed themselves.

This is a picture of a tomato. The tomato is an example of a C3 Plant because they do not need to be in very sunny environments for photosynthesis, they need to be in a cool environment. A C3 Plant is one that is efficient at photosynthesis in a cool and wet climate.

This is a picture of corn. The corn is an example of a C4 Plant because the photosynthetic apparatus of maize is exposed to high temperature stress. A C4 plant is a plant that enters the Calvin Cycle when cycling carbon dioxide into four carbon sugar compounds. A C4 plant can include corn, pineapple, sugar cane, etc.

This is a picture of a rolly-polly. A rolly-polly is an example of a detritivore. A detritivore is an animal that feeds on dead organic material and breaks down dead plant and animal matter while providing nutrients to the ecosystem. Rolly pollies are detritivores because they consume organic material, primarily eating dead plants or animals.

This is a picture of a turtle. A turtle is an example of an ectotherm because as a cold blooded animal, they get heat from their surroundings like water. An ectotherm is an organism who regulates its body temperature and whose body temperature relies on external heat sources.

This is a picture of a dog. A eukaryote is a living organism that contains cells and has a nucleus in which its genetic material and DNA is in the form of chromosomes. A dog is an example of a eukaryote because it has eukaryotic cells and has its genetic material organized in a membrane bound nucleus.
