Study Notes
Organisms
- Living entities classified as plants, animals, or bacteria.
Energy Pyramid
- Diagrams illustrating energy transfer between levels of a food chain.
Consumers
- First-level consumers: Organisms that feed on producers such as plants and algae.
- Second-level consumers: Organisms that prey on first-level consumers.
- Third-level consumers (tertiary): Organisms that feed on second-level consumers.
Competition
- Occurs when organisms vie for limited resources in the same ecological niche.
Camouflage
- Adaptation that allows animals to blend into their environment to evade predators.
Symbiosis
- Long-term interactions between different species of organisms.
Mutualism
- A symbiotic relationship benefiting both organisms involved.
Parasitism
- A symbiotic relationship where one organism benefits at the expense of another.
Extinction
- Occurs when the last member of a species has died out.
Threatened Species
- Species that are in jeopardy of becoming endangered.
Pollution
- Any harmful waste that contaminates ecosystems.
Acid Rain
- Rain produced when water vapor combines with pollutants from vehicles and factories.
Deforestation
- The removal of trees for timber, leading to habitat loss.
Conservation
- The practice of preserving natural resources and protecting ecosystems.
Recycling
- The process of recovering materials from waste to create new products.
Reducing Resource Use
- Minimizing usage of resources, exemplified by utilizing reusable shopping bags.
Reuse
- Extending the life of items by finding new uses for them instead of discarding.
Photosynthesis Requirements
- Plants and algae require sunlight, carbon dioxide, water, and chlorophyll to perform photosynthesis.
Biotic Components
- Living entities in an ecosystem include plants, animals, and algae.
Abiotic Components
- Non-living factors such as soil, minerals, air, and water that affect ecosystems.
Scavengers
- Organisms that consume dead or decaying matter, such as vultures and isopods.
Decomposers
- Fungi, bacteria, and mushrooms that break down dead organic material and recycle nutrients.
Primary Energy Source
- The sun serves as the main energy source for life on Earth.
Role of Decomposers
- Decomposers enrich soil fertility through the decomposition of organic matter.
Resource Limitation and Competition
- If resources are scarce, organisms in the same niche will compete for survival.
Habitat Destruction
- The leading cause of extinction today, resulting from the degradation of natural habitats.
Mutualism Example
- A cleaner fish that cleans a shark’s teeth benefits from food and safety, while the shark gains dental hygiene.
Parasitism Example
- A flea that feeds on a dog benefits from nourishment, while the dog suffers no advantage.
Terrestrial Ecosystems
- Diverse biomes include deciduous forests, tropical rainforests, grasslands, deserts, taiga, and tundras.
Deciduous Forest
- A biome characterized by trees that lose their leaves annually, experiencing moderate temperatures and rainfall.
Tropical Rainforest
- A biodiverse ecosystem known for its immense variety of plant and animal life.
