ENVRIONMENTAL PROBLEMS
OVERFISHING
Overfishing occurs when fish populations are excessively harvested, often leading to the decline of fish stocks and disrupting marine ecosystems.
URBAN SPRAWL
Urban sprawl is the uncontrolled and expansive growth of urban areas into surrounding rural or undeveloped land, often resulting in the loss of natural habitats and increased environmental degradation.
ACID RAIN
Acid rain is precipitation (rain, snow, or fog) that is unnaturally acidic due to pollutants like sulfur dioxide and nitrogen oxides, causing harm to ecosystems, water bodies, and structures.
GENETIC ENGINEERING
Genetic engineering involves the manipulation of an organism's genetic material using biotechnology techniques to produce desired traits, impacting agriculture, medicine, and industry.
OZONE LAYER DEPLETION
Ozone layer depletion refers to the thinning of the ozone layer in the Earth's stratosphere, mainly caused by human-made chemicals called ozone-depleting substances, leading to increased ultraviolet radiation.
OCEAN ACIDIFICATION
Ocean acidification is the increase in acidity in the Earth's oceans, primarily caused by the absorption of excess carbon dioxide from the atmosphere, posing threats to marine life.
NITROGEN CYCLE
The nitrogen cycle is the natural process through which nitrogen in the atmosphere is converted into various forms, essential for plant growth and ecosystem functioning.
CLIMATE CHANGE
Climate change is the long-term alteration of Earth's climate, primarily due to human activities like burning fossil fuels, deforestation, and industrial processes, leading to global temperature increases.
LOSS OF BIODIVERSITY
The loss of biodiversity refers to the decline in the variety and abundance of plant and animal species in a specific habitat, often caused by human activities, habitat destruction, and pollution.
DEFORESTATION
Deforestation is the clearing or removal of large areas of forests, often for agriculture, logging, or urban development, leading to habitat loss, climate change, and biodiversity decline
.
WASTE DISPOSAL
Waste disposal involves the proper management and elimination of waste materials to prevent environmental pollution and health hazards, emphasizing recycling and responsible disposal methods.
GENERATING UNSUSTAINABLE WASTE
Generating unsustainable waste involves producing excessive amounts of non-biodegradable waste, contributing to environmental pollution and ecosystem harm.
NATURAL RESOURCE DEPLETION
Natural resource depletion occurs when essential resources, such as fossil fuels, minerals, and forests, are used at an unsustainable rate, jeopardizing their availability for future generations.
OVERPOPULATION
Overpopulation occurs when the number of people in a given area exceeds the capacity of the environment to support sustainable living, leading to various social, economic, and environmental challenges.
GLOBAL WARMING
Global warming refers to the long-term increase in Earth's average temperature, primarily caused by human activities such as burning fossil fuels, deforestation, and industrial processes.
SOIL DEGRATION
Soil degradation is the deterioration of soil quality, often due to improper agricultural practices, deforestation, and industrial activities, leading to decreased fertility and productivity.
LAND POLLUTION
Land pollution involves the degradation of the Earth's surface through activities like littering, dumping waste, and industrial practices, negatively impacting ecosystems and human health.
WATER POLLUTION
Water pollution occurs when contaminants enter water bodies, making them unsafe for humans and wildlife.
AIR POLLUTION
Air pollution is the presence of harmful substances in the air, often caused by human activities like burning fossil fuels, which can harm the health of living organisms.
PUBLIC HEALTH ISSUE
A public health issue is a concern that affects the health and well-being of a population, encompassing various factors such as diseases, environmental hazards, and social determinants.
TYPES OF NUTRIENT CYCLE
OXYGEN CYCLE
The oxygen cycle involves the production of oxygen through photosynthesis by plants and algae, its release into the atmosphere, and its utilization by organisms during respiration
PHOSPHORUS CYCLE
The phosphorus cycle is the movement of phosphorus through rocks, soil, water, and living organisms, including processes like weathering, absorption, assimilation, and sedimentation.
NITROGEN CYCLE
The nitrogen cycle is the movement of nitrogen through the atmosphere, soil, and living organisms, encompassing nitrogen fixation, nitrification, assimilation, ammonification, and denitrification.
SULFUR CYCLE
The sulfur cycle entails the circulation of sulfur through the atmosphere, soil, and living organisms, involving processes like weathering, bacterial transformations, and volcanic emissions.
CARBON CYCLE
The carbon cycle involves the exchange of carbon dioxide between living organisms, the atmosphere, oceans, and soil, including processes like photosynthesis, respiration, and decomposition.
WATER CYCLE
The water cycle is the continuous movement of water between the atmosphere, oceans, land, and living organisms, involving processes like evaporation, condensation, precipitation, and runoff.

NUTRITIONAL RELATIONSHIP IN AN ECOSYSTEM
FOOD CHAIN
A food chain is a straight line of who eats whom in an ecosystem. Each link depends on the one before and provides food for the next. It's a basic way energy and nutrients move through nature.
FOOD WEB
A food web is a tangle of connected food chains in an ecosystem. It shows how different creatures eat and interact with each other, revealing the flow of energy and nutrients through many paths in nature.
A BALANCED ECOSYSTEM HAS THREE FUNDAMENTAL CHARACTERISTICS
Conversion of
energy to glucose
Constant source of
energy
Organic matter and nutrients recycling

NTERTIDAL ZONE
The intertidal zone is the part of the shore that gets wet and dry with each tide. Here, creatures are specially adapted to handle both wet and dry conditions, making it a unique and tough place to live.
ESTUARIES
Estuaries are where rivers meet the ocean, mixing freshwater with salty seawater. They have dynamic water flow, diverse ecosystems, and are vital habitats for many types of sea life.
Refers to living components of an ecosystem, including plants, animals, fungi, and microorganisms, that interact with one another.
Relates to non-living factors in an ecosystem, encompassing physical and chemical elements such as temperature, water, sunlight, and soil
