Hydrosphere and how humans negatively impact it - Water on the earths surface
Plastic and garbage from landfills pollutes the water and kills aquatic animals.
Biosphere and how humans negatively impact it - Where life can exist within the
lithosphere, hydrosphere, and atmosphere.
Forest fires and deforestation pollutes the biosphere and destroys habitats, leading to
the endangerment of many species.
Lithosphere and how humans negatively impact it - Earth's solid surface
On an every day basis humans litter extremely large amounts of waste that pollutes the
lithosphere.
Atmosphere and how humans negatively impact it - The layer of gas that surrounds the
earth
Human built factories expel large amounts of gas and smoke that pollutes the
atmosphere.
Ecosystem - All the living organisms and their physical and chemical environment.
What is an ecological niche? - The role or job of a species in an ecosystem.
How do animals get energy from the sun? - Plants use the process of photosynthesis to
create their own energy, sugars and carbohydrates. When animals consume plants we
are also consuming the sun's energy from the plant and we animals use cellular
respiration to create energy which originally came from the sun.
Chemical equation for photosynthesis - carbon dioxide + water + __light energy_> sugar
+ oxygen
Chemical equation for cellular respiration - sugar + oxygen -> carbon dioxide + water +
energy
Producers in aquatic ecosystems - algae and cynobacteria
What is cellular respiration? - The process by which sugar and oxygen are converted
into carbon dioxide, water and energy for the cell.
Radiant energy - energy that travels through space
light energy - visible forms of radiant energy
How is the sun's energy absorbed? - 30% is reflected by clouds or earth
19% is absorbed by the atmosphere and clouds
51% is absorbed by land and ocean
0.023% absorbed by plants in photosynthesis
Why is biomass at the top of the food pyramid lower compared to biomass at the
bottom? - There is more biomass at the bottom of the pyramid to support the energy
requirements of the higher trophic levels as they cannot create their own energy.
