Grains
Grains are small, hard, dry seeds harvested for human or animal food. They are a staple food in many cultures and provide a major source of energy and nutrients.
Types of Grains:
- Whole Grains: These grains contain the entire grain kernel - the bran, germ, and endosperm. Examples include brown rice, quinoa, and whole wheat.
- Refined Grains: These grains have been processed to remove the bran and germ, resulting in a finer texture and longer shelf life. Examples include white rice and white flour.
Nutritional Value:
Grains are a good source of carbohydrates, which provide energy for the body. They also contain important nutrients such as fiber, B vitamins, and minerals like iron and magnesium.

Ecosystems: Interactions, Energy, and Dynamics
Use evidence and scientific reasoning to explain how characteristic animal behaviors (e.g., building nests to protect young from cold, herding to protect young from predators, attracting mates for breeding by producing special sounds and displaying colorful plumage, transferring pollen or seeds to create conditions for seed germination and growth) and specialized plant structures (e.g., flower brightness, nectar, and odor attracting birds that transfer pollen; hard outer shells on seeds providing protection prior to germination) affect the probability of successful reproduction of both animals and plants.
