Food chain â a sequence of
organisms related to one another
as prey and predator.
7. Food chain â a sequence of organisms related to one another as prey and predator.
Parts of the food chain:
1. producers
⢠usually a photosynthetic organism
(make own food from sunlight)
â˘are at the base of the food chain
â˘All energy comes from them
â˘usually green - chlorophyll
8. 2.Consumer âderives nutrients
and energy from consuming
other organisms.
Includes:
⢠herbivores or primary
consumers â they consume
plants
9. 2. Consumers
Includes:
⢠carnivores or secondary
consumers - they consume
other animals that once
consumed plants.
10. 2. Consumers
Includes
⢠omnivores
-who can be primary or
secondary consumers
- eat plants or other animals.
11. ⢠Omnivores who can be primary or secondary consumers
- eat plants or other animals.
3. Decomposers - are
organisms that breakdown
dead or decaying
organisms.

12. We will begin our course study
of biology in the field of botany.
Reasons for studying botany:
1. many medications are derived from
plants
2. important to industry (lumber,
paper, clothing,acetate, rayon, etc)
3. all food eaten by man comes directly or
indirectly from plants
