Studying Our Living Planet 3.1 What Is Ecology? Studying Our Living Planet Ecology: the scientific study of interactions among and between organisms and their physical environment.

Interactions within the biosphere produce a web of interdependence between organisms and the environments in which they live.

Ecology and Economics Economics is concerned with interactions based on money. Economics and ecology share the same word root. Human economics and ecology are linked. Humans live within the biosphere and depend on ecological processes to provide such essentials as food and drinkable water that can be bought and sold for money.

Population: group of individuals of same species living in same area

Community: many populations living together in a defined area. https://www.youtube.com/watch?v=RVJduMnXAns

Ecosystem: all the organisms that live in a place, together with their physical environment like water, climate, rocks, dirt…..

Biome: group of ecosystems that share similar climates and typical organisms

Biosphere: all life on Earth and all parts of the Earth where life exists, including land, water, and the atmosphere. It extends 8 km above Earth’s surface to as far as 11 km below the surface of the ocean.

Biotic Factors: the biological influences on organisms - any living part of the environment with which an organism might interact: * animals * plants * mushrooms * bacteria. Biotic factors for a bullfrog: algae it eats as a tadpole, herons that eat bullfrogs, and other species competing for food or space.

Abiotic Factor: the physical components of an ecosystem - any nonliving part of the environment: Sunlight heat Precipitation Humidity wind or water currents soil type… Example: A bullfrog could be affected by abiotic factors such as water availability, temperature, and humidity.

3.2 Energy, Producers, and Consumers All organisms need energy No organism can create energy - it can only use energy from other sources. Organisms need energy for growth, reproduction, and metabolic processes.

Sunlight is the energy source for most life on Earth Photosynthesis captures light energy for chemical reactions that convert CO2 and H2O into O2 and C6H12O6 (carbohydrates). This process adds oxygen to the atmosphere and removes carbon dioxide. Primary producers (Autotrophs) produce of energy-rich compounds that are used by other organisms. Examples: plants, algae, and photosynthetic bacteria, most commonly cyanobacteria
