What are abiotic factors?
Click to flip
Abiotic factors are non-living components of the environment, such as temperature, light, and water, that affect living organisms.
Click to flip
How does temperature influence the metabolism of organisms?
Click to flip
Temperature affects the rate of biochemical reactions, with higher temperatures generally increasing metabolism up to a certain point, beyond which it may denature enzymes.
Click to flip
Give an example of an organism adapting to seasonal changes.
Click to flip
Bears hibernate in winter to conserve energy when food is scarce, lowering their metabolic rate significantly.
Click to flip
What role does light play in the life of plants?
Click to flip
Light is essential for photosynthesis, the process by which plants convert light energy into chemical energy.
Click to flip
How can pH levels in water bodies affect aquatic life?
Click to flip
Extreme pH levels can harm aquatic organisms by affecting their bodily functions and may lead to death or decreased biodiversity.
Click to flip
What is an example of a biotic factor?
Click to flip
A biotic factor is any living component that affects another organism, such as predators, parasites, or competitors.
Click to flip
How do predators influence prey populations?
Click to flip
Predators help control the population size of prey species and can affect their spatial distribution and behavior.
Click to flip
What is ecological succession?
Click to flip
Ecological succession is the natural process by which the structure of a biological community evolves over time.
Click to flip
Name an environmental factor that affects terrestrial plants.
Click to flip
Soil composition is a key environmental factor, influencing nutrient availability and water retention.
Click to flip
Why is water considered a critical environmental factor for organisms?
Click to flip
Water is essential for physiological processes such as nutrient transport, temperature regulation, and chemical reactions.
Click to flip
Explain how altitude affects species distribution.
Click to flip
Higher altitudes tend to have cooler temperatures and less oxygen, restricting species that can survive and adapt to such conditions.
Click to flip
How can anthropogenic factors influence natural environments?
Click to flip
Anthropogenic factors like pollution, deforestation, and urbanization alter habitats, often leading to reduced biodiversity.
Click to flip
What impact does humidity have on organisms?
Click to flip
Humidity affects water loss through transpiration in plants and can influence thermal regulation in animals.
Click to flip
How do wind patterns affect plant growth?
Click to flip
Wind can influence plant growth by dispersing seeds, pollens, and influencing temperature through evaporation.
Click to flip
Why is biodiversity considered a measure of environmental health?
Click to flip
Biodiversity provides resilience against environmental changes and is indicative of a balanced ecosystem.
