1. sequence construct a model of the hierarchy of ecological organization. your completed model should have six levels.
2. synthesize describe how chemical reactions are important to the movement of energy and matter in an ecosystem.

Explanation:

3.

The six - level hierarchy of ecological organization is: organism, population, community, ecosystem, biome, biosphere. An organism is an individual living thing. A population is a group of the same species in an area. A community is all populations in an area. An ecosystem includes the community and its abiotic factors. A biome is a large area with similar climate and characteristic plant and animal communities. The biosphere is the global sum of all ecosystems.

Chemical reactions are crucial as they drive energy - transfer and matter - cycling in ecosystems. Photosynthesis is a chemical reaction where plants convert light energy into chemical energy (glucose), storing energy. Respiration is another chemical reaction where organisms break down glucose to release energy. Nutrient cycling also involves chemical reactions, like the nitrogen - fixing reactions that convert atmospheric nitrogen into forms usable by plants.

Answer:

Organism, Population, Community, Ecosystem, Biome, Biosphere
