eco systems and biomes Flashcards
Ecosystem
An ecosystem is a community of living organisms (biotic factors) interacting with their non-living environment (abiotic factors). Ecosystems can be as small as a pond or as large as a forest, and they play a crucial role in maintaining ecological balance.
Biotic Factors
Biotic factors are living components of an ecosystem, including plants, animals, fungi, bacteria, and other microorganisms. The interactions between these organisms influence the ecosystem’s structure and function.
Abiotic Factors
Abiotic factors are non-living components of an ecosystem, such as temperature, sunlight, soil, water, and air. These factors influence the distribution and behavior of biotic components within the ecosystem.
Food Chain
A food chain represents the transfer of energy and nutrients through a series of organisms in an ecosystem. It typically consists of producers (plants), consumers (animals), and decomposers (organisms that break down dead organic matter).
Food Web
A food web is a complex network of interconnected food chains in an ecosystem. It shows the multiple paths of energy flow and the interactions between various organisms at different trophic levels.
Trophic Level
A trophic level is a position in the food chain or food web hierarchy, representing the feeding status of organisms. Producers are at the first trophic level, followed by primary consumers, secondary consumers, and so on.
Biome
A biome is a large geographic area characterized by its climate, vegetation, and wildlife. Examples include deserts, forests, grasslands, and tundras. Biomes are defined by similar abiotic conditions and adapted biotic communities.
Deciduous Forest
A deciduous forest biome is characterized by trees that shed their leaves seasonally. These forests experience four distinct seasons, with moderate temperatures and a diverse range of plant and animal species.
Desert Biome
A desert biome is characterized by arid conditions, low precipitation, and high temperatures. Plants and animals in deserts are adapted to conserve water, and biodiversity is often lower compared to other biomes.
where is a Rainforest Biome found and what is its characteristics?
A rainforest biome, found near the equator, experiences high temperatures and abundant rainfall. It is characterized by lush vegetation, diverse plant and animal life, and high levels of biodiversity.
Tundra Biome
The tundra biome is characterized by low temperatures, permafrost (frozen soil), and a short growing season. Vegetation is limited to hardy plants, and animals are adapted to cold conditions.
Conservation
Conservation involves the sustainable management of natural resources and ecosystems to maintain biodiversity and ecological balance. Conservation efforts aim to protect species, habitats, and overall ecosystem health.
