Interdependence of Organisms
Energy Flow in the Ecosystem
The Water Cycle
Evaporation
Water from oceans, rivers, and lakes is heated by the sun and turns into vapor, rising into the atmosphere
Transpiration
Plants release water vapor into the air through small openings in their leaves
Condensation
Water vapor cools and condenses into tiny droplets, forming clouds
Precipitation
Water falls back to the Earth in the form of rain, snow, sleet, or hail.
Infiltration and Runoff
Some water soaks into the ground (infiltration) while excess water flows over the surface (runoff) into bodies of water.
Importance
The water cycle is crucial for maintaining ecosystems, supporting plant and animal life, and regulating climate
The Carbon Cycle
Photosynthesis
Plants absorb carbon dioxide (CO2) from the atmosphere and convert it into organic matter (glucose) using sunlight.
Respiration
Animals and plants release CO2 back into the atmosphere through respiration as they metabolize organic matter for energy.
Decomposition
Decomposers break down dead organic matter, releasing CO2 back into the soil and atmosphere.
Combustion
Burning fossil fuels and biomass releases stored carbon back into the atmosphere as CO2.
Carbon Sequestration
Some carbon is stored in oceans, forests, and soil, helping to regulate atmospheric CO2 levels.
Importance
The carbon cycle is essential for regulating Earth's climate and supporting life by providing the carbon necessary for organic molecules.
The Oxygen Cycle
Photosynthesis
Similar to the carbon cycle, plants produce oxygen as a byproduct of photosynthesis, releasing it into the atmosphere.
Respiration
Animals and humans consume oxygen for cellular respiration, producing CO2 as a byproduct.
Decomposition
Decomposers also consume oxygen while breaking down organic matter, contributing to the cycle.
Importance
The oxygen cycle is vital for the survival of aerobic organisms and maintaining atmospheric oxygen levels.
The Nitrogen Cycle
Nitrogen Fixation
Certain bacteria convert atmospheric nitrogen (N2) into ammonia (NH3), which can be used by plants.
Nitrification
Ammonia is converted into nitrites (NO2-) and then nitrates (NO3-) by nitrifying bacteria, making nitrogen available to plants.
Assimilation
Plants absorb nitrates and incorporate nitrogen into organic molecules (proteins, nucleic acids).
Ammonification
Decomposers break down organic matter, releasing ammonia back into the soil.
Denitrification
Denitrifying bacteria convert nitrates back into N2 gas, returning nitrogen to the atmosphere.
Importance
The nitrogen cycle is crucial for producing amino acids and nucleic acids, which are essential for all living organisms.
The Energy Cycle
Energy Capture
Plants (producers) capture solar energy through photosynthesis, converting it into chemical energy stored in glucose.
Energy Transfer
Herbivores (primary consumers) eat plants, transferring energy up the food chain. Carnivores (secondary consumers) eat herbivores, continuing the transfer.
Energy Loss
At each trophic level, energy is lost as heat due to metabolic processes, limiting the number of trophic levels in an ecosystem.
Decomposition
Decomposers break down dead organisms, returning energy and nutrients to the soil, which supports new plant growth.
Importance
The energy cycle is fundamental for sustaining life, as it governs the flow of energy through ecosystems and supports all biological processes
