Study Notes
Weather and Climate
- Weather refers to the atmospheric conditions at a specific time and location.
- Climate is the long-term average of temperature and precipitation for a region.
Greenhouse Effect
- The greenhouse effect involves the retention of heat in Earth's atmosphere through gases like carbon dioxide, methane, and water vapor.
Climate Zones
- Polar zones experience cold climates due to low-angle sunlight.
- Temperate zones feature moderate climates situated between polar regions and tropics.
- Tropical zones are characterized by warm climates with direct sunlight year-round.
Biotic and Abiotic Factors
- Biotic factors involve biological influences affecting organisms in an ecosystem.
- Abiotic factors are nonliving elements, such as temperature and nutrients, that shape ecosystems.
Habitat and Niche
- A habitat is the area an organism inhabits, containing both biotic and abiotic influences.
- A niche defines the full range of conditions and lifestyle of an organism in its environment.
Competition and Interaction
- Resources are essential for life, including water, food, and light.
- The competitive exclusion principle states that two species cannot occupy the same niche simultaneously.
- Predation is the interaction where one organism hunts and consumes another.
- Symbiosis describes close relationships between species, including mutualism (both benefit), commensalism (one benefits, the other is unaffected), and parasitism (one benefits at the expense of the other).
Ecological Succession
- Ecological succession is the gradual change in community composition following disturbances.
- Primary succession occurs in lifeless areas without soil; it starts with pioneer species.
- Secondary succession follows disturbances that leave the soil intact.
Aquatic Ecosystems
- Plankton are minute organisms drifting in aquatic environments, including phytoplankton (photosynthetic organisms) and zooplankton (tiny animals).
- Wetlands are ecosystems with seasonal or permanent water coverage.
- Estuaries form where freshwater rivers meet the ocean, rich in nutrients and biodiversity.
- Salt marshes and mangrove swamps are types of coastal wetlands, characterized by their salt-tolerant vegetation.
Oceanic Zones
- The photic zone is the upper part of the ocean, where sunlight penetrates.
- The aphotic zone remains dark, under the photic layer, with no sunlight reaching it.
Biomes and Their Characteristics
- Biomes are categorized groups of ecosystems that share similar climates and dominant species.
- Tolerance refers to an organism's ability to thrive despite unfavorable conditions.
- Microclimates are variations in climate within small localized areas.
Forest Structures
- Canopy refers to the dense layer formed by tree tops in a rainforest.
- Understory is the layer beneath the canopy comprising shorter trees and vines.
Types of Trees
- Deciduous trees shed their leaves during specific seasons.
- Coniferous trees have needle-like leaves and produce cones.
Soil and Ground Conditions
- Humus is organic material formed from decaying plant matter.
- Taiga is a biome with cold winters and mild summers, allowing ground thawing.
- Permafrost is a permanently frozen subsoil layer found in tundra regions.
