Ecological Balance

How ecosystems can be affected: Population increase or decrease, and natural causes like wildfires, tornadoes, earthquakes, hurricanes, floods and volcanic eruptions. Man-made issues include deforestation, overuse of boats and motorized water vehicles.

Biomass

ONLY 10% OF THE ENERGY IS RETAINED

Example: a biomass pyramid is used to show energy transfer between organisms - The sun gives plants energy. A herbivore eats the plant, a carnivore then eats the herbivore.

biomass is a measure of the total mass of living organisms within an ecosystem. In other words, it is a measurement of energy

Ecosystems
