4 Major fields of biology
 botany – study of plants
zoology – study of animals

4. 4 Major fields of biology

zoology – study of animals
human anatomy and physiology -
study of physical structures and the
functions of the human body.

ecology – the study of
interactions between organisms
and their environment and each
other.

6. ecology – the study of interactions between organisms and their
environment and each other.
Food chain – a sequence of
organisms related to one another
as prey and predator.

7. Food chain – 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)
•are at the base of the food chain
•All energy comes from them
•usually green - chlorophyll

8. 2.Consumer –derives nutrients
and energy from consuming
other organisms.
Includes:
• herbivores or primary
consumers – 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.
Includes:

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
