Forces - Forces and EnergyCFU | Forces and EnergyScience ~ Year 7 ~ Quiz ~ Forces and Energy ~ Sound7th Science: HW 4.5 Forces and energyCreate a multiple choice test (10 questions with answers) from the following text: The Environment The environment is the combination of forces and conditions that surround and influence living and non-living things. Human beings’ environment includes such factors as temperature, food supply and other people that surround them. A plant’s environment may be made up of soil, sunlight, and animals that will eat the plant. A rock’s environment may be made up of seaweed, water and fish. Non-living environmental factors, such as temperature and sunlight, make up the abiotic (non-living) environment. Living organisms such as seaweed and food, make up the biotic environment. Both the abiotic and biotic environments interact to make up the total environment of living and non-living things. Ecology Ecology studies the relationships between living things and their environment. No living thing, plant or animal, lives alone. Every living thing depends in some way upon certain other living and non-living things to survive. The study of ecology increases our understanding of the world and all its creatures. This is crucial because humanity’s survival and well-being depend on relationships that exist on a world-wide basis: changes in distant parts of the world affect us and our environment. One concern of ecologists is the rate at which we are using up natural resources such as coal, gas, and oil. Along with scientists, they are searching for ways to use sunlight and atomic energy for fuel and power as alternative energy sources. Ecology also studies how many living organisms there are on Earth and how they are distributed. It also considers non-living physical factors of the environment, for example the presence of water, as these can influence where organisms decide to live. It is also important to know which organisms share the same environment, as they may need each other to survive. This kind of information helps ecologists to conserve our natural world, protecting the habitat of animals that are in danger of extinction, or trying to reduce pollution and global warming. Ecosystems Ecosystems are biological communities of all living things like plants, animals and organisms in a specific area that interact with each other and with the non-living forms present in their environment. They are the foundations of the biosphere and determine the health of the entire planet’s system. A biosphere is a global ecosystem, containing many different kinds of ecosystems.Energy and Forces Review for TestEnergy and Forces ReviewEnergy and Forces
