Ecosystem Energy Flow All energy initially comes from sunlight.

Ecosystem Energy Flow All energy initially comes from sunlight. Radiant Energy: the type of energy, including light that travels to Earth from the Sun through space.

Ecosystem Energy Flow All energy initially comes from sunlight. Radiant Energy: the type of energy, including light that travels to Earth from the Sun through space. Where does the energy go?

Ecosystem Energy Flow Where does the energy go?

Ecosystem Energy Flow Where does the energy go? -almost 70% is absorbed by ground, water, and atmosphere and turned into heat

Ecosystem Energy Flow Where does the energy go? -almost 70% is absorbed by ground, water, and atmosphere and turned into heat -almost 30% is reflected back into space

Ecosystem Energy Flow Where does the energy go? -almost 70% is absorbed by ground, water, and atmosphere and turned into heat -almost 30% is reflected back into space -0.023% is absorbed by plants in photosynthesis

Ecosystem Energy Flow Photosynthesis: the process in which the Sun's energy is converted into chemical energy

Ecosystem Energy Flow Photosynthesis: the process in which the Sun's energy is converted into chemical energy Word equation: carbon dioxide + water light energy sugar + oxygen

Ecosystem Energy Flow Photosynthesis: the process in which the Sun's energy is converted into chemical energy Word equation: carbon dioxide + water light energy sugar + oxygen producer: an organism that uses photosynthesis to make its own energy-rich food using the Sun's energy

Ecosystem Energy Flow Cell respiration: the process by which sugar is converted into energy useable by the cell

Ecosystem Energy Flow Cell respiration: the process by which sugar is converted into energy useable by the cell -all cells, plant and animal, do cell respiration

Ecosystem Energy Flow Cellular respiration: the process by which sugar is converted into energy useable by the cell -all cells, plant and animal, do cell respiration Word equation: sugar + oxygen carbon + water + energy dioxide

Ecosystem Energy Flow Cell respiration and photosynthesis are complementary processes -so the atoms are continually recycled

Ecosystem Energy Flow Consumer: an organism that obtains its energy by consuming other organisms, or the products of other organisms

Ecosystem Energy Flow Types of consumers: herbivore: eats only plants

Ecosystem Energy Flow Types of consumers: herbivore: eats only plants carnivore: eats only animals

Ecosystem Energy Flow Types of consumers: herbivore: eats only plants carnivore: eats only animals omnivore: eats plants and animals

Ecosystem Energy Flow Types of consumers: herbivore: eats only plants carnivore: eats only animals omnivore: eats plants and animals scavenger: eats dead animals

Ecosystem Energy Flow Types of consumers: herbivore: eats only plants carnivore: eats only animals omnivore: eats plants and animals scavenger: eats dead animals decomposer: eats decaying organisms
