Formulas
Characteristics of Living Beings: Movement, Growth, Respiration, Reproduction, Excretion, Response to Stimuli.
These are fundamental characteristics that differentiate living beings from non-living things. For example, living beings exhibit growth and respond to stimuli, whereas non-living things do not.
Photosynthesis: 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
Carbon dioxide and water, in the presence of sunlight, are converted into glucose and oxygen. This process is vital for plant nutrition and oxygen production.
Germination Conditions: Water + Air + Optimal Temperature = Successful Germination.
Seeds require water, air, and suitable temperature for germination. This formula highlights the essential conditions for seed growth.
Respiration: Glucose + Oxygen → Carbon Dioxide + Water + Energy
In respiration, glucose reacts with oxygen to release energy, carbon dioxide, and water. This process is crucial for all living organisms.
Growth Rate = (Final Size - Initial Size) / Time
This measures how fast an organism grows over time, demonstrating the characteristic of growth in living beings.
Equations
Biodiversity Index = (Number of species) / (Total number of individuals)
This equation helps assess the variety of life forms in a specific area, aiding in understanding ecological health.
Ecosystem Productivity = Primary Production + Secondary Production
This defines the total amount of biomass produced by plants (primary) and animals (secondary) in an ecosystem.
Population Growth = Births - Deaths + Immigration - Emigration
This equation calculates how a population changes over time, considering various factors affecting the number of individuals in a group.
Energy Transfer Efficiency = (Energy Available after Transfer) / (Energy Available before Transfer) × 100%
This equation assesses how much energy is retained in an ecosystem during trophic transfers, important in ecology.
Respiration Rate = (Volume of oxygen consumed) / (Time)
This measures how quickly an organism uses oxygen, reflecting its metabolic activity and health.
