Study Notes
Ecosystems and Communities
- Ecosystems are made up of interactions between living organisms and their environment.
- Abiotic factors include temperature, humidity, pressure, and soil type.
- Biotic factors include plants, animals, and microorganisms.
- The text focuses on understanding ecosystems and communities through their components and interactions.
Populations
- A population consists of individuals of the same species living in a specific place.
- Factors that affect population size include gene flow, intraspecific competition, density, and abundance.
Environmental Factors
- Conditions: Physical and chemical factors can affect populations. Examples include temperature, humidity, soil acidity, and toxic substances.
- Disturbances: Sudden or chronic events impact populations. Examples include fire, floods, landslides, hurricanes, parasites, and invasive species.
Resources
- A resource is anything an organism needs to survive.
- Resources can be biotic (pollinators, prey) or abiotic (water, solar energy).
- Interspecific competition occurs when individuals of different species compete for the same resources.
Predation
- Predation is a relationship where one organism (predator) eats another organism (prey).
- It has a positive impact on the predator's survival and reproduction.
Energy Flow
- Energy is the ability to do work.
- In ecosystems, light energy is transformed into chemical energy through photosynthesis.
- Chemical energy is stored in the bonds of molecules in plants and animals.
- Biomass energy is the energy stored in living organisms.
- Respiration releases energy from organic matter.
Primary Production
- Gross Primary Production (GPP) is the total amount of energy fixed by autotrophs through photosynthesis.
- Net Primary Production (NPP) is the energy available to other organisms after respiration.
- NPP represents the amount of energy and food biomass available to higher trophic levels.
Climate Factors
- Latitude: Influences solar radiation. Equator receives most direct sunlight. Tropical regions are warm, poles are cold.
- Altitude: Height above sea level. Lower atmospheric pressure and temperature at higher altitudes.
- Relative Humidity: Percentage of water vapor in the air. Affected by temperature. Measured with a hygrometer.
- Cloudiness: Percentage of sky covered by clouds. Affects weather and solar radiation.
