Chapter 12: The Antioxidant Nutrients - start march 4 at ~ 42 mins - Slide 1 * we produce a lot of reactive oxygen species (ROS) from reactions in the body‚ especially from energy metabolism * these ROS can damage the molecules in the body‚ especially in dna and rna molecules and lipids. This can have serious consequences on the health of the individual * one of the ways that the body deals with ROS is by having compounds that can help to neutralize the radicals or protect the body

influencing climate‚ nutrient dynamics and water movement. Forests are found all over the world‚ and they provide valuable economic and environmental services. Information About a Forest Ecosystem A forest ecosystem is the community formed by plants and animals of that particular area that interact with the chemical and physical features of the environment in which they live. The Amazon rain forest ecosystem is an example of a forest ecosystem. This ecosystem is home to a wide variety of plant and animal
Premium Tropical rainforest Forest Rainforest
The average temperature of the tropical rainforest is 80°F. The average precipitation is 60 to 160 inches that is distributed evenly throughout the year. The tropical rainforest is suitable to many plant and animal life. It contains the most biodiversity in the world. Approximately 15 million plant and animal species life in the tropical rainforest biome. The tropical rainforest has three different layers of the canopy‚ the understory‚ and the ground story. The tropical rainforest has a very dense

living (biotic) and the non-living (abiotic) components of the natural world is its subject matter. Processes like primary production‚ nutrient cycling‚ and various niche construction energies are sustained by the biodiversity within them and regulate the flux of energy and matter through an environment. Biodiversity is the variety and also the abundance of plants and animals in a particular environment and the processes that are functionally enriched by ecological interactions. The ecosystem

Temperature also plays a big row in everyday life. For example‚ if the weather is good (no snow) it gives opportunity for more livestock to grow‚ and more carbon-diode to plants and also enough oxygen. But if the weather is cold or it snows‚ trees will be frozen‚ less amount of oxygen‚ carbon-dioxide and sometimes affect the growth of plants and animals. All species in a habitat regulate their own temperature in adapting to the system i.e. one species may be cold blooded or warm blooded and these temperatures
Premium Ecology Natural environment Environment
An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚ they can come in any size but usually encompass specific‚ limited spaces (although

there as there is plenty of food. These animals include treefrogs and snakes. Understory Layer- Little sunshine reaches this area so the plants have to grow larger leaves to reach the sunlight. Many animals live there including jaguars and leopards. There are also a large amounts of insects that live here. Forest Floor- It’s very dark down here. Almost no plants grow in this area‚ as a result. Since hardly any sun reaches the forest floor things begin to rot quickly. A leaf that might take one

BSAC3 BIOLOGY 1. How plants grow and develop? Just as humans have essential needs for survival‚ all plants require several basic elements to grow and thrive‚ including… Soil minerals (the more nutrient-rich the soil‚ the better the plant will grow) Water Air (carbon dioxide‚ hydrogen and oxygen) Sunlight Proper soil temperature Proper air temperature How much a plant needs of each element initially depends on the plant’s original habitat. For example‚ a rainforest plant that requires consistently

Species – A species is a group of organisms with similar characteristics‚ which can interbreed and produce viable‚ fertile offspring. Habitat – A habitat is the environment in which a species normally lives or the location of a living organism. Population – A population is a group of organisms of the same species‚ who
