Study Notes

Environmental Damage Phenomena

Run-off collects water, filling watersheds and dams.
Soil erosion occurs due to water movement, causing environmental concerns.
Wind affects water vapor movement and creates localized wind forms.
Acid rain results from water vapor contacting contaminants like sulfur and nitric acid, harming living organisms.
Eutrophication arises when fertilizers run-off into water bodies, leading to rapid plant growth that outcompetes other species.
Drought, or “El Niño,” occurs with insufficient precipitation, causing water scarcity.
Flash floods, or “La Niña,” happen when excessive precipitation accumulates quickly in areas unable to drain.
Sinkholes can form when water storage basins deplete due to low precipitation, leading to sudden collapses.

Soil and Physiographic Factors

Soil texture (sand, silt, loam, clay) influences plant and animal types supported in the area.
Soil temperature impacts organic matter decomposition rates.
Soil water, pH, and nutrient availability affect biological activities.
Physical characteristics of an area (altitude, sunlight, rainfall, slope) shape vegetation types.

Biotic Components and Nutritional Relationships

Autotrophs capture energy from sunlight to produce organic compounds; they act as producers.
Heterotrophs require preformed organic nutrients, consuming other organisms; they are categorized into herbivores, carnivores, and omnivores.
Decomposers, like bacteria and fungi, break down dead matter to return nutrients to the ecosystem.

Nutritional Relationships Overview

Competition: Two organisms utilize the same resources.
Parasitism: One organism benefits at the host's expense.
Predation: Predators feed on prey.
Commensalism: One organism benefits without affecting the other.
Protocooperation: Both organisms benefit, but it's not obligatory.
Mutualism: Both benefit, and the relationship is obligatory.

Ecosystem Roles

Producers: Convert simple organic molecules through photosynthesis (e.g., grasses, trees).
Consumers: Use organic matter for food; include herbivores, carnivores, omnivores, scavengers, and parasites.
Decomposers: Recycle organic material into inorganic forms (e.g., bacteria, fungi).
Detritivores: Consume decaying organic matter for nourishment.

Food Web and Trophic Levels

Primary Producers: Plants like Acacia and start grass.
Primary Consumers: Herbivores such as termites, giraffes, and zebras.
Secondary Consumers: Carnivores like lions and cheetahs thrive on primary consumers.

Energy Flow and Thermodynamic Principles

Cellular respiration releases heat to the environment while transferring energy to carnivores.
Energy is also allocated to detritus feeders through processes like death, excretion, and defecation.
The First Law of Thermodynamics states energy cannot be created or destroyed, only transformed from one form to another.
