Identify plants and animals in an ecosystem (i.e., beach, woodland, marsh, meadow). Examine the life cycles of the plants and animals and identify factors in the ecosystem that are beneficial or harmful to the organisms at various stages in its life cycle (i.e., young fish are small which makes them able to hide in plants, but this characteristic also makes them more vulnerable to predators).
The natural world consists of a diversity of organisms that transmit their characteristics to future generations. Living things reproduce, develop, and transmit traits, and theories of evolution explain the unity and diversity of species found on Earth. Knowledge of genetics, reproduction, and development is applied to improve agriculture and human health.
Organisms reproduce, develop, have predictable life cycles, and pass on heritable traits to their offspring.
