2. Components of Environment, Ecology, Ecosphere, and Biosphere 1. ENVIRONMENT The environment refers to the sum total of all external conditions and influences affecting the life, development, and survival of an organism or a group of organisms. It encompasses both biotic (living) and abiotic (non-living) factors

3. components of the environment: Biotic Components: All living organisms Examples: plants , animals, fungi, bacteria, and other microorganisms. Abiotic Components: All non-living organisms Examples: temperature , humidity, sunlight, soil, air, water, and geological factors .

4. Chemical Environment : This refers to the composition and concentration of chemicals and elements in the environment, such as nutrients, minerals, pollutants, and gases . Social and Cultural Environment : In addition to the natural environment, the human-made environment, including infrastructure, technology, and cultural practices, can significantly impact the overall environment.

5. ECOLOGY Ecology is the scientific study of the interactions between organisms and their environment. It focuses on understanding how organisms relate to each other and their surroundings Ecology encompasses various levels of organization: Individual Ecology : The study of an individual organism's interactions with its environment, including its behavior, physiology, and adaptations Examples: Animal behavior, physical adaptations. Population Ecology : Investigates the dynamics of populations of a single species, including factors like birth rates, death rates, and population growth . Community Ecology : Examines the interactions among different species living in the same area, including competition, predation, and mutualism.

6. Ecosystem Ecology : Studies the flow of energy and matter within ecosystems, including the roles of producers (plants), consumers (animals), and decomposers (microorganisms ). Landscape Ecology : Analyzes the spatial arrangement of ecosystems and the impact of human activities on the landscape . Global Ecology : Explores the interactions between ecosystems on a global scale, including the study of biogeochemical cycles and climate change.

7. ECOSPHERE The term " ecosphere " is not a widely used or recognized concept in ecology. However, it may refer to the entire Earth's ecosystem or the sum total of all ecosystems on our planet. Essentially, it suggests a holistic view of the interconnectedness of all living organisms and their environments on Earth .

8. BIOSPHERE The biosphere is the portion of Earth that supports life. It includes all ecosystems, biomes, and habitats where living organisms can be found. The biosphere encompasses lithosphere (Earth's crust ) hydrosphere (water bodies), and atmosphere (air and gases). It extends from deep within the Earth's crust to the highest reaches of the atmosphere. The biosphere is characterized by its ability to sustain life and the interconnectedness of all living organisms within it.
