Photosynthesis
• Life depends on the sun
• Requires: Carbon dioxide and water
• Produces: glucose, oxygen and releases some water

Cellular Respiration
• The process of cells breaking down food to yield energy
• Requires: Glucose and oxygen
• Produces: Energy,Carbon dioxide and water.

They need each other

Feeding Relationships
• Producers (Autotrophs)- Plants
• Consumers (Heterotrophs)- organisms that get their food by consuming other organisms
![Page 6: 3.1 Energy Flow in Ecosystem Mrs. Trimble Mrs. Perryman.](https://reader035.fdocuments.in/reader035/viewer/2022072006/56649f585503460f94c7cf31/html5/thumbnails/6.jpg)
Types of Consumers
• Herbivore- eats plants• Carnivore- eats
animals• Omnivore- eats both
plants and animals• Decomposer- breaks
down dead organisms in an ecosystem, returning them to nature

Energy Transfer
• Food Chain- sequence in which energy is transferred from one organism to the next

Energy Transfer
• Food Web- shows many feeding relationships

Biomass Pyramid
• Trophic Level- each step in the energy trophic level
Producers
Primary Consumers/ Herbivore
Secondary Consumer/ Consumers

Energy Loss within an ecosystem
• 90% of the energy at each level is due to normal daily activity.
• Only 10% of the biomass is passed onto the next level.
10,000 g/m2
1,000g/m2
100 g/m2
