Extinction occurs when all members of a species die off and the species disappears from Earth permanently. Examples of extinct animals include dinosaurs, dodos, mammoths, and the Bali tiger. Climate change, habitat destruction, overhunting, pollution, deforestation, invasive species, and overpopulation are factors that can lead to species extinction by reducing habitats, changing ecosystems, and depleting resources. When invasive species are introduced to new ecosystems, they can significantly alter the environment and drive other native species to extinction. Overpopulation stresses resources as population growth outpaces food supply.

Changes in ecosystem
Environments are constantly changing, both slowly over long periods of time through processes like drought, and rapidly due to events like floods and fires. These changes impact the plants and animals living there. Organisms respond by migrating to find new habitats with more suitable conditions, like elephants traveling to find water and grass. Others adapt to survive the changes, such as predators hunting different prey or frogs burying themselves in dry conditions. If organisms cannot migrate or adapt, they may not survive the environmental changes.
3 2 major components of an ecosystem
Organisms obtain nutrients in different ways: some produce their own through photosynthesis, others consume other organisms, and decomposers recycle nutrients by breaking down remains. Within ecosystems, producers use photosynthesis to make food, consumers obtain food by eating producers or each other, and decomposers release nutrients by breaking down waste. Nutrient recycling and energy flow from the sun allow ecosystems to be sustained.

The document emphasizes that environmental problems are human-caused and that both large and small actions can help address these issues.
Environment
This document discusses environmental issues and citizen responsibilities. It identifies problems like deforestation, global warming, endangered species loss and pollution. It also lists responsibilities citizens have to help the environment such as saving water, electricity and fuel, not polluting, and respecting plants and animals.
Ayush biomagnification
Biomagnification is the accumulation of chemicals in living organisms at higher concentrations than in the environment. For example, DDT accumulates in zooplankton and moves up the food chain to small fish, then larger fish, and finally fish-eating birds, which experience the highest levels. This affects human health through cancer, organ damage, and birth defects. It also disrupts food chains and harms reproduction in marine life. Causes include agricultural and industrial chemicals, mining, and sewage runoff, which introduce toxins like mercury and selenium into waterways where they biomagnify up the aquatic food chain.
Ecological problems
This document outlines ecological problems and proposes a plan to introduce and address global environmental issues. It identifies the main ecological problems as air pollution from vehicles and industry, water pollution from dumping waste, radiation issues like Chernobyl, threats from earthquakes, deforestation, and loss of biodiversity. The document's aims are to determine key problems, provide advice on environmental protection, and suggest solutions. Tasks include showing different ways of addressing ecological challenges.

Modern enviorenmental problems
The document discusses several modern environmental problems including pollution, deforestation, desertification, habitat loss, and extinction of animals. It defines pollution as the accumulation of harmful substances in the air, water, and ground. Deforestation is described as the disappearance of forests caused by cutting down and burning trees, as well as pollution and fires. Desertification is defined as the transformation of landscapes into desert areas when the soil becomes dry and poor. Habitat loss occurs when natural areas are destroyed to make room for housing and industry.
3 4 ecosystem cycles
Nutrient cycles like water, carbon, and nitrogen cycle through ecosystems and are powered by solar energy. These cycles connect all organisms and involve reservoirs where nutrients accumulate. Human activities like agriculture, deforestation, and burning fossil fuels are altering nutrient cycles by changing land use, polluting water sources, and increasing carbon dioxide emissions. This disrupts natural cycling patterns and ecosystem functions.
Biodiversity and climate change
Climate change and biodiversity are closely linked: climate change has severe direct and indirect impacts on biodiversity and is predicted to be a dominant driver of future biodiversity loss; at the same time, the loss of biodiversity magnifies the adverse effects of climate change.
Natural resources & human effects on the earth
This document discusses natural resources and how humans impact the environment. It defines renewable resources like water, air and forests that regenerate and non-renewable resources like oil, coal and minerals that do not regenerate quickly. While humans can harm the environment through pollution, destruction of habitats, and overuse of resources, actions like recycling, renewable energy and environmental protection laws help mitigate damage and protect natural resources for future generations.
Global warming
Global warming is caused by greenhouse gases like carbon dioxide and methane trapping heat in the atmosphere, causing the Earth's temperature to rise. As temperatures increase, the climate will change dramatically with some areas experiencing droughts and others severe flooding. Melting polar ice caps will also raise sea levels and threaten coastal cities. While higher CO2 levels may increase crop growth, the overall impacts of climate change are expected to be harmful. Both natural factors like the sun's intensity and human activities that release greenhouse gases contribute to global warming. Reducing emissions, waste, and deforestation can help mitigate the problem.
Environmental biology
The document discusses various ways that human activities negatively impact the environment. It describes how increasing population leads to intensification of agriculture, urbanization, and industrialization, which damage habitats, pollute air and water, and cause soil erosion. Specific issues covered include deforestation, monoculture farming, pollution from fossil fuel use and acid rain. Solutions proposed include more sustainable agricultural practices, reducing pollution by using cleaner fuels and technologies, and afforestation.
Biodiversity and evolution
The document discusses biodiversity and the IUCN Red List of Threatened Species. It describes the nine categories of species classifications in the Red List, ranging from extinct to least concern. Major causes of extinction are then outlined, including climate change, habitat loss, pollution, and wildlife trade, which can be natural factors or due to human activity. Steps to prevent further extinction and preserve biodiversity are proposed, such as reducing waste, supporting organic farming, and minimizing plastic use.
Contaminacion Ambiental=Ingles=
The document discusses various types of environmental pollution and destruction caused by human activities:
1) Air, water, and soil are polluted by emissions from vehicles, factories, and improper disposal of trash and chemicals.
2) Natural resources like land and wildlife are overexploited through unsustainable farming, deforestation, and overhunting and overfishing.
3) Habitats are destroyed through activities like construction of roads and dams, which remove trees and farmland, and through the introduction of invasive species to new ecosystems.
Environmental problems and solutions
Many environmental problems are caused by human actions including pollution, deforestation, desertification, and habitat loss. Pollution is the accumulation of harmful substances in the air, water, and ground. Deforestation is the disappearance of forests from cutting down trees. Desertification is the transformation of landscapes into desert areas as the soil becomes dry and poor. Habitat loss occurs when natural areas are destroyed for housing and industry. Children can help address these issues by reducing garbage production, avoiding cutting down trees, and protecting natural areas.
15 Chapter
The document summarizes different types of ecosystems including aquatic ecosystems. It discusses succession and climax communities in ecosystems and describes various biomes like tundra, taiga, temperate forests, tropical rainforests, grasslands, and deserts. It also covers freshwater ecosystems like rivers, streams, lakes, ponds, and wetlands as well as saltwater ecosystems including open oceans, coral reefs, seashores, and estuaries.
Water biomes and succession
Biomes are large groups of ecosystems that share similar climax communities. There are terrestrial and aquatic biomes. Aquatic biomes include marine and freshwater biomes. Marine biomes can be divided into photic and aphotic zones. Estuaries are where freshwater and saltwater mix, containing salt marshes that provide nursery habitats. Freshwater biomes include lakes and ponds with different zones based on depth and sunlight availability.
Deforestation
Deforestation is the permanent destruction of forests to make land available for other uses. Forests play an important role in the water and carbon cycles by absorbing and releasing water and carbon slowly over time. Removing forests disrupts these cycles. Deforestation reduces the number of trees that store carbon, allowing more carbon dioxide to remain in the atmosphere and contribute to climate change. It also destroys habitats for many living things. Common causes of deforestation include converting land to agriculture, uncontrolled fires, overharvesting of fuelwood, mining, and climate change itself.
Vocabulary environment
Acid rain is harmful to the environment. Aerosol sprays are a major cause of pollution in homes. The Earth's atmosphere is a thin layer of gases surrounding the Earth. Carbon is contained in all plants and animals. Catalytic converters have been compulsory in cars in Britain since 1993 to reduce emissions.
Earth day
This document discusses various environmental problems facing the planet and potential solutions. It identifies the top 10 most endangered animals, including gorillas, tigers, and rhinos. Deforestation, air pollution from burning fossil fuels, and plastic pollution are mentioned as major issues. Water, land, and air are all being polluted by human activities like improper waste disposal, agricultural runoff, and oil spills. Simple solutions proposed include planting trees, using less water and energy, recycling, and organizing litter cleanups. The importance of Earth Day on April 22nd is highlighted.
NE Mosaic approach: Managing habitats for species - introduction
Introduction to the Mosaic approach: A series of visual, interactive guides designed to help land managers manage habitats in a way that supports multiple species by developing “mosaics” of different environmental features at a landscape scale, within a range of habitat types.
Our environment needs to be take care like our baby
Our health and lives are at stake due to environmental toxins in the air, water, and food from an unbalanced and unsustainable environment polluted by over-consumption and loss of natural resources. The growing threat of climate change means we must reassess our environmental impact and choices, as the earth is the only planet we have and future generations deserve to enjoy its beauty and resources. If humans do not begin caring for the environment by limiting consumption and protecting habitats and species, severe weather events and loss of potential cures will only increase while our resources dwindle.
Ch 3 ecosystems
Tropical rainforests are found near the equator, cover 6% of the land surface, and are home to 50% of the world's plant and animal species. However, at least 50% have been destroyed or disturbed by human activities like cutting down trees, growing crops, grazing livestock, and building settlements. The consequences are a decrease in biodiversity as species go extinct, accelerated global warming due to fewer trees removing carbon dioxide from the atmosphere, and changes to regional weather patterns that can lead to more tropical grasslands.

Ecosystems are constantly changing due to natural events like volcanoes and hurricanes, as well as human activities such as deforestation and pollution. These changes can make it difficult for living things to survive if they cannot accommodate to the changes, move to new habitats, or become endangered or extinct. Examples of accommodation include animals changing their diets or using new materials for shelter, while moving away involves searching for new places with sufficient food, water and shelter. If organisms cannot meet their needs by accommodating or moving, they may become extinct like the dinosaurs or passenger pigeon.

The planet earth
The document discusses several factors that are damaging the Earth's ecosystem and environment, including ecosystem changes, extinction of animals, global warming, pollution, and climactic changes. It provides explanations and examples of each factor, how they harm the planet, and some ways human activities can be adjusted to reduce negative impacts and help protect the Earth's resources for the future.
Response to change
When an ecosystem is disturbed through natural or human causes, it undergoes ecological succession over time as species populations change. Succession can be primary on new lands or secondary in previously inhabited areas. In secondary succession, smaller pioneer species arrive first, followed by larger species that feed on them as habitat changes. Eventually a climax community develops if the ecosystem remains undisturbed. Human activities like pollution and overharvesting of resources can disrupt succession and damage ecosystems. A sustainable approach preserves biodiversity, habitats, and uses resources renewably so they are available for future generations.

Unit 6 The Biosphere
The biosphere is the largest ecosystem and includes all living things on Earth. Organisms fall into different trophic levels including producers, primary consumers, secondary consumers, tertiary consumers, predators, scavengers, parasites, and decomposers. Food chains and webs show how different species are connected through feeding relationships. Loss of biodiversity occurs when species go extinct due to factors like climate change, pollution, habitat loss, and overexploitation of resources. Protected areas like national parks and biosphere reserves aim to protect endangered wildlife and their habitats from these threats.

30how does using natural resources affect the environment?
Natural events like volcanoes, earthquakes, hurricanes, droughts and tsunamis can cause ecosystems to change. People can also impact ecosystems through deforestation, pollution, overpopulation, and oil spills. When ecosystems change, organisms may need to accommodate by finding new resources, some species may go extinct if unable to adapt, and conservation efforts can help sustain resources through reducing consumption, reusing materials, and recycling.
students sample
The document defines environment and classifies it into eight components: water, temperature, food, light, air, soil, plants, and animals. It describes how each component contributes to ecosystems and explains their importance. It also discusses how human activity like deforestation, pollution from industries and improper waste disposal leads to environmental degradation, which causes issues like increased diseases, ozone depletion, and global warming. Lastly, it emphasizes the need to protect the environment through judicious resource use, cleanliness, and inculcating environmental values to achieve sustainable development.
ecosystem
Ecosystems can change slowly over time through processes like eutrophication where organic matter and nutrients build up, or more suddenly due to natural disturbances from events like hurricanes, fires, or volcanic eruptions. Succession describes how ecological communities develop and change over time. Primary succession occurs on new areas without soil as pioneer species move in and help form soil. Secondary succession happens on existing soils, where grasses are typically followed by other plants and forests over 100 years. Climax communities represent stable, mature ecosystems dominated by well-adapted species until a further disturbance occurs. Biodiversity increases as succession progresses, making the ecosystem more stable.

Biodiversity presentation
Biodiversity refers to the variety of species on Earth, which provides resources and helps maintain the atmosphere and soil fertility. Loss of biodiversity occurs when species disappear from ecosystems, altering interactions and functions. The main threats to biodiversity are habitat loss, introduced species, pollution, population growth, and climate change, which can cause mass extinctions that profoundly impact Earth.
Biodiversity presentation
Here are five sentence answers to the questions:
Introduced species can negatively affect biodiversity in an ecosystem by competing with and preying upon native species, often driving some native species to extinction. They disrupt the natural balance and niche relationships that have developed over long periods of time.
Pollution can affect biodiversity in an ecosystem by poisoning organisms, destroying habitats, and causing reproductive problems that weaken populations and make species more vulnerable to extinction. Pollution like oil spills or pesticides can kill many organisms at once or accumulate in the food chain.
If the current mass extinction continues at its predicted rate, it will drastically reduce global biodiversity and disrupt ecosystem functions and services that humans rely on. Whole ecosystems may collapse as keystone

Prehistory.pdf
Prehistory spans from 2 million years ago to the invention of writing around 3,000 BC. It encompassed over 2 million years where humans lived as hunter-gatherers and began basic tool use and fire, while history refers to the last 5,000 years. The Paleolithic and Neolithic periods saw major changes - in Paleolithic times humans hunted and gathered wild plants, lived nomadically in caves, and used stone tools, whereas in Neolithic times humans domesticated animals and plants, lived sedentary lives in houses near rivers, and used stone and wood tools as well as pottery.
Digestive system
We chew food in our mouth and it passes to the esophagus and stomach. The stomach produces gastric juices and mixes the food with juices from the liver, pancreas, and stomach to create a thick liquid. This liquid passes to the small intestine where nutrients are absorbed and then to the large intestine where waste is stored and water is absorbed before waste is released through the anus. The digestive system breaks down food into nutrients and removes waste.
How the ear works
There are three main parts of the ear - the outer, middle, and inner ear. Sound waves enter the outer ear and cause the eardrum to vibrate, transmitting vibrations through three small bones in the middle ear. These vibrations then reach the cochlea in the inner ear, where they are converted to electrical signals that are sent by the auditory nerve to the brain, which interprets the signals and allows us to hear.
Vocabulary actions
This document lists a variety of activities including going fishing, sailing or windsurfing, playing games like chess, board games or computer games, building a robot, dressing up, knitting, sewing, skipping and kicking.
Rivers
The document describes the three stages of a river's course from its source to its mouth. In the upper course, the river is narrow and fast-flowing from its source. In the middle course, the river widens and slows with meanders and sometimes tributaries. In the lower course, the river empties into another river, lake, sea or ocean at its estuary and mouth.
Superlatives
This document lists superlative adjectives describing size, speed, temperature and location for various objects around the world. It provides the longest, biggest, tallest, fastest, coldest and hottest examples, including the longest river (Nile), biggest animal (blue whale), tallest animal (giraffe), fastest animal (cheetah), coldest continent (Antarctica) and hottest place (Sahara Desert). Locations are also given for items like the highest mountain (Mount Everest in Asia) and smallest country (Vatican City in Europe).
Comparatives
This document provides examples of comparative adjectives that describe size, age, height, volume and speed. It lists adjective pairs such as long-short, big-small, old-young, and loud-quiet and shows how to form comparisons using "-er than" or being "faster/slower than". Examples include the Burj Khalifa being higher than the Eiffel Tower and cheetahs being faster than other animals.
Plants
The three main parts of a plant are the leaves, stem, and roots. The roots absorb water and minerals from the soil and fix the plant in place. The stem transports these nutrients from the roots to the leaves. In the leaves, photosynthesis takes place, mixing water, minerals, carbon dioxide, and sunlight to produce glucose and release oxygen.
Weather and climate
Weather is the changing atmospheric conditions from day to day, such as temperature, wind, and precipitation. Climate is the average weather conditions in an area over a long period of time. The factors that influence weather are temperature, humidity, wind, and precipitation, which are measured using instruments like thermometers, hygrometers, anemometers, and rain gauges. Weather changes daily but climate remains consistent over decades.
Climates in the world
There are three main climatic areas in the world: polar, temperate, and tropical. The polar climate is found at the North and South Poles and is characterized by extremely cold winter temperatures below -50°C and cool summers around 5°C. The temperate climate experiences cold winters and hot summers along with four distinct seasons. The tropical climate lies between the Tropic of Cancer and Capricorn and has year-round hot weather along with a dry and rainy season.
