The Controversy Over Dinosaur Metabolism. This paper provides an overview and analysis of the controversy over dinosaur metabolism and the ongoing debate concerning whether dinosaurs were endothermic or ectothermic. Following a brief introductory overview of the implications of endothermy versus ectothermy for species physiology and survival, the essay examines the main arguments and evidence directly related to dinosaur metabolism, the analysis also considers the implications of the recent findings on the KT event and the mass extinctions for dinosaur metabolism.
Plants and Life on Earth What is the environment? The environment is everything that lives on Earth plus the air, sun, water, weather, and the Earth itself. Sing a Song about the Role of Plants! Teachers—download lesson plans to use in your classroom!
Plants help the environment and us! Plants make food Plants are the only organisms that can convert light energy from the sun into food. And plants produce ALL of the food that animals, including people, eat.
The animals that give us meat, such as chickens and cows, eat grass, oats, corn, or some other plants. Plants make oxygen One of the materials that plants produce as they make food is oxygen gas. This oxygen gas, which is an important part of the air, is the gas that plants and animals must have in order to stay alive.
When people breathe, it is the oxygen that we take out of the air to keep our cells and bodies alive. All of the oxygen available for living organisms comes from plants. Plants provide habitats for animals Plants are the primary habitat for thousands of other organisms. Animals live in, on, or under plants.
Plants provide shelter and safety for animals. Plants also provide a place for animals to find other food. As a habitat, plants alter the climate. On a small scale, plants provide shade, help moderate the temperature, and protect animals from the wind. Plants help make and preserve soil In the forest and the prairie, the roots of plants help hold the soil together.
This reduces erosion and helps conserve the soil. Plants also help make soil. Soil is made up of lots of particles of rocks which are broken down into very small pieces. When plants die, their decomposed remains are added to the soil. This helps to make the soil rich with nutrients.
Plants provide useful products for people Many plants are important sources of products that people use, including food, fibers for clothand medicines. Plants also help provide some of our energy needs.
In some parts of the world, wood is the primary fuel used by people to cook their meals and heat their homes. Many of the other types of fuel we use today, such as coal, natural gas, and gasoline, were made from plants that lived millions of years ago.
Plants beautify Plants, because of their beauty, are important elements of out human world. When we build houses and other buildings, we never think the job is done until we have planted trees, shrubs, and flowers to make what we have built much nicer.Wild biological resources are domesticated through modern agriculture, are used in prevention of plant and animal diseases, etc.
These impart productive value to the biodiversity.
The consumptive and the productive uses of biodiversity have economic value. Importance. The study of plant uses by rainforests, forests with colorful autumn leaves, and festivals such as Japan's and America's cherry blossom festivals.

Englewood Cliffs, NJ: Prentice Hall. Four important plant/animal interactions are explored here: plant/herbivore, plant/pollinator, plant/disperser, and other examples of mutualism. Plant/Herbivore Relationships Herbivory is an interaction in which a plant or portions of the plant are consumed by an animal.
The study of plant-animal interactions has been a key role in development of ecology hence it has been carried out for a long time. They are also key constituents of biodiversity, which is termed as a variation of life form in a particular ecosystem. On a larger scale, such as in tropical rainforests, plants actually change the rainfall patterns over large areas of the earth's surface.
