echinoderms like starfish
How can the levels of biological organism be described? - ANSWER -Successive,
broadest to smallest
What are the levels of biological organization? - ANSWER -biosphere,
ecosystems, communities, populations, organisms, organ systems, organs, tissues,
cells, molecules and atoms
What is the biosphere? - ANSWER -Broadest level of organization that
encompasses earth and atmosphere, and all capable of sustaining living organisms
What is an ecosystem? - ANSWER -A system of living and non living things in a
region
What are some examples of ecosystems? - ANSWER -Grasslands, forests, deserts,
coral reefs, soils, climate conditions
