3. 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.

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

Organisms respond to their environments and can change their environments, producing an ever- changing biosphere.

6. 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.

7. Levels of Organization
Individual organism:
one organism of a certain species – Emperor Penguin

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

12. Community: many populations living together in a defined area.

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

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

18. 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.

21. 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.

22. 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.

25. 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.

27. 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
