ecology – the study of interactions between organisms and theirenvironment and each other.Food chain – a sequence oforganisms related to one anotheras prey and predator.
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
2.Consumer –derives nutrientsand energy from consumingother organisms.Includes: • herbivores or primary consumers – they consume plants
2. Consumers Includes:• carnivores or secondary consumers - they consume other animals that once consumed plants.
2. Consumers Includes • omnivores -who can be primary or secondary consumers - eat plants or other animals.
• Omnivores who can be primary or secondary consumers - eat plants or other animals.3. Decomposers - are organisms that breakdown dead or decaying organisms. Includes:
We will begin our course study of biology in the field of botany. Reasons for studying botany:1. many medications are derived from plants2. important to industry (lumber, paper, clothing,acetate, rayon, etc)3. all food eaten by man comes directly or indirectly from plants
