Environmental Conditions
Environmental conditions refer to the physical, chemical, and biological factors that influence the growth and survival of organisms in a particular area. These factors can include temperature, humidity, sunlight, soil type, and the presence of other living organisms.
Physical Factors
- Temperature: The average temperature in an area can affect the types of organisms that can survive there. Extreme temperatures can be harmful to living organisms.
- Light: The amount of sunlight available in an environment can determine the types of plants that can grow there, which in turn affects the animals that can survive in the area.
- Water: The availability of water is crucial for the survival of all living organisms. Some organisms can survive in very dry environments, while others require a constant water supply.
Chemical Factors
- pH: The acidity or alkalinity of the soil or water in an environment can affect the availability of nutrients to plants and other organisms.
- Nutrients: The presence of essential nutrients such as nitrogen, phosphorus, and potassium in the soil can impact the growth of plants and the animals that depend on them.
- Pollutants: Human activities can introduce pollutants into the environment, which can have detrimental effects on the organisms living there.
Biological Factors
- Competition: Organisms in an environment compete with each other for resources such as food, water, and space.
- Predation: The presence of predators can influence the behavior and population sizes of prey species.
- Symbiosis: Some organisms form mutually beneficial relationships with each other, such as the relationship between bees and flowering plants.
Study Guide
When studying environmental conditions, consider the following questions:
- How do physical factors like temperature and light influence the distribution of organisms?
- What role do chemical factors such as pH and nutrient availability play in shaping ecosystems?
- How do biological factors like competition and predation impact the interactions between different species?
- What are the potential effects of human activities, such as pollution, on environmental conditions?

Life Science
Interdependence - A. Plants and animals, including humans, interact with and depend upon each other and their environment to satisfy their basic needs. B. Both human activities and natural events can have major impacts on the environment. C. Energy flows from the sun through producers to consumers.
Compare and contrast adaptations displayed by animals and plants that enable them to survive in different environments such as life cycles variations, animal behaviors and physical characteristics.
