Ecology Pyramid of Numbers, Biomass Pyramid, Ecosystem Lesson PowerPoint
11 likes5,706 views
The document outlines concepts related to ecological pyramids, including the pyramid of numbers and biomass, demonstrating the decrease in energy as one moves up trophic levels. It emphasizes the importance of documenting scientific observations and includes activities for measuring biomass and simulating energy flow. The recommendation is made that planting crops yields more available energy than grazing animals on limited land.

- 42. • Answer – We should plant crops. There is more available energy in producing vegetables than animals. – We may get 10,000 plants. – The field may support one small cow which will just give a small amount of milk, even less energy if we use our one animal for BBQ.
