Forest soils are moist‚ but without protection from sun-blocking tree cover they quickly dry out. Trees also help conserve the water cycle by returning water vapor back into the atmosphere. Trees remove carbon dioxide from the atmosphere through photosynthesis. Cutting down forests will cause a decline in photosynthetic activity which results in the

A cycle is a biological pathway or process in which the end product of one cycle becomes the starting point for the next cycles Write an essay about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration‚ the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration‚ the production

Fourth is that it can cause damage to the plants since floor wax contains volatile substances that can block plants from doing photosynthesis Despite the recent efforts by various organizations efforts to educate the public about the toxic dangers of floor wax no one seems to believe them due to the effectiveness of the modern floor wax but still its harming our environment.

containing carbon. Since it is a cycle‚ it can begin anywhere. Let us start with the atmosphere. The forms of carbon in the atmosphere are methane and carbon dioxide. Plants (living organisms) take in the carbon dioxide and sunlight‚ undergoing photosynthesis to make sugar molecules (carbon fixation) for the plant’s energy purposes. The plants then release oxygen back into the atmosphere‚ and animals breathe it in. The soil‚ plants‚ and animal’s respiration‚ releases carbon from the terrestrial biosphere

PROTIST STUDY GUIDE 1. Where can Protists primarily be found? Most Protists can be found in wet areas‚ tree trunks and other organisms 2. What niche do Protists fill in an ecosystem? Protists have a big role in marine life‚ it serves as housing for many animals and food for many as well. 3. What are the 3 categories of Protists? Animal-like protists plant-like protists and fungus-like protists 4. What are the 4 types of Protozoa and how does each one move? Ciliates : Have hundreds of

terrestrial environment as well as aquatic one. Photosynthesis in Aquatic Plants and Land Plants Process of producing food with light energy remains the same for both aquatic and terrestrial plants. They both require the same raw materials – carbon dioxide and water to synthesis glucose. Terrestrial plants can absorb carbon dioxide from atmospheric air and water from the soil through their roots. Obviously land plants can work through photosynthesis easily without any special adaptations. But terrestrial

essential to our survival‚ provide habitats for wild animal and contribute to the development of economy. To begin with‚ it is undeniable that forests help us to survive‚ because trees in forests supply oxygen for people and animals. Through the photosynthesis process‚ trees combine carbon dioxide and light to create their own food and oxygen‚ so this process is very crucial to all kind of animals in our planet‚ which include human. If the forests disappear‚ it will be a disaster because we will lack

entire planet is an ecosystem). Energy‚ water‚ nitrogen and soil minerals are other essential abiotic components of an ecosystem. The energy that flows through ecosystems is obtained primarily from the sun. It generally enters the system through photosynthesis‚ a process that also captures carbon from the atmosphere. By feeding on plants and on one another‚ animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial
