Maine Standards

ME.E. The Living Environment: Students understand that cells are the basic unit of life, that all life as we know it has evolved through genetic transfer and natural selection to create a great diversity of organisms, and that these organisms create interdependent webs through which matter and energy flow. Students understand similarities and differences between humans and other organisms and the interconnections of these interdependent webs.
E.1. Biodiversity: Students compare living things based on their behaviors, external features, and environmental needs.
E.1.b. Describe the changes in external features and behaviors of an organism during its life cycle.
E.2. Ecosystems: Students describe ways organisms depend upon, interact within, and change the living and non-living environment as well as ways the environment affects organisms.
E.2.b. Describe that organisms all over the Earth are living, dying, and decaying and new organisms are being produced by the old ones.
E.2.c. Describe some of the ways in which organisms depend on one another, including animals carrying pollen and dispersing seeds.
E.3. Cells: Students describe how living things are made up of one or more cells and the ways cells help organisms meet their basic needs.
E.3.b. Compare how needs of living things are met in single-celled and multi-celled organisms.
