  1. 3. the process by which an organism becomes better suited to its environment over time through changes in its traits. These traits can be physical, like the shape of a beak or the color of fur, or behavioral, like migration patterns or mating rituals.
  2. 4. the practice of cultivating soil, growing crops, and raising animals for food, fiber, medicinal plants, and other products used to sustain and enhance human life. It involves a range of activities such as planting, harvesting, breeding, and managing livestock, as well as maintaining soil health and water resources. Agriculture plays a vital role in feeding populations and supporting economies worldwide.
  3. 8. refers to the idea that organisms best adapted to their environment are more likely to survive, reproduce, and pass on their advantageous traits to the next generation.
  4. 9. the process by which humans intentionally breed plants or animals for specific traits or characteristics. Unlike natural selection, where environmental pressures influence which traits are passed on, artificial selection is driven by human choices.
  5. 10. organisms that hunt, capture, and kill other organisms (prey) for food. They are a key part of ecosystems, as they help regulate the population of prey species and maintain balance in the food chain. Examples of predators include lions hunting zebras, hawks catching mice, or sharks preying on fish.
Down
  1. 1. refers to the young or descendants produced by an organism through reproduction. Offspring inherit genetic traits from their parents and can be animals, plants, or other living organisms. Examples include puppies born to dogs, kittens born to cats, or seeds produced by plants.
  2. 2. group of individuals of the same species living in a specific area at a given time. These individuals can interbreed and share the same environment, and the size and characteristics of a population can change over time due to factors like birth rates, death rates, immigration, and emigration.
  3. 5. the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.
  4. 6. distinguishing characteristics or features of an organism, which can be physical, behavioral, or physiological. Traits are typically inherited from parents through genes and can vary within a population. Examples of traits include eye color, leaf shape, fur pattern, or hunting behavior.
  5. 7. refers to organisms that are hunted, captured, and eaten by predators. In a food chain, prey serves as a food source for predators. Examples of prey include rabbits being hunted by foxes, fish being eaten by larger fish or birds, and small insects being eaten by frogs or spiders.
