Study Notes
Photosynthesis and Energy Flow
- Photosynthesis is a crucial biochemical reaction occurring in leaves and blades of grass, converting sunlight into chemical energy.
- Energy from sunlight fuels ecosystems, supporting life by transforming solar energy into food through producers.
Role of Producers
- Producers, or autotrophs, convert inorganic molecules and energy into organic compounds, providing essential food sources for other organisms.
- Types of autotrophs:
- Photoautotrophs: Use sunlight to synthesize food via photosynthesis (e.g., plants, algae, cyanobacteria).
- Chemoautotrophs: Obtain energy from chemical reactions to produce food; include certain bacteria and archaea, often found in extreme environments.
Types of Photoautotrophs
- Terrestrial Ecosystems: Plants like trees and grasses.
- Aquatic Ecosystems: Algae such as diatoms and seaweed.
- Bacteria: Cyanobacteria serve as photoautotrophs in both terrestrial and aquatic environments.
Consumers in Ecosystems
- Consumers, or heterotrophs, rely on organic matter from other organisms for energy.
- Types of consumers:
- Herbivores: Eat plants or algae (e.g., deer, rabbits).
- Carnivores: Consume other animals (e.g., lions, hawks); some are obligate carnivores and only eat meat.
- Omnivores: Eat both plants and animals (e.g., humans, pigs).
Unique Consumers
- Carnivorous plants like pitcher plants and Venus flytraps utilize photosynthesis but also capture insects for nutrients in nutrient-poor soils.
Decomposers and their Role
- Decomposers recycle energy and nutrients by breaking down dead organic matter and waste, returning inorganic molecules to the environment for reuse by producers.
- Types of decomposers:
- Scavengers: Consume soft tissues of dead animals (e.g., vultures).
- Detritivores: Feed on detritus, such as dead leaves and feces; include earthworms and bottom-feeding fish.
- Saprotrophs: Final decomposers that consume remaining organic matter, primarily fungi and bacteria; fungi are unique for their ability to decompose wood.
Example of a Notable Decomposer
- Pacific Banana Slug represents a key decomposer in California's redwood forests, contributing to soil replenishment by consuming fallen organic material.
