2.1.1 Distinguish between biotic and abiotic components of an ecosystem * Biotic factors in an ecosystem are living‚ biological factors that may influence an organism in an ecosystem * Abiotic factors are non-living‚ physical factors that may influence an organism in an ecosystem 2.1.2 Define the term trophic level * The position that an organism occupies in a food chain‚ or a group of organisms in a community that occupy the same position in food chains 2.1.3 Identify and explain

activities‚ which include growth‚ intermediary metabolism‚ protein synthesis‚ and reproduction (cell division). Chloroplasts Contain a green pigment known as chlorophyll which absorbs light energy (needed in the plants food making process of photosynthesis.) It does this by converting the water and carbon dioxide‚ found in the cell‚ into sugars and carbohydrates. Therefore the chloroplasts covert light energy into chemical energy.

Evolutionary trees convey a lot of information about a group’s evolutionary history. Biologists are taking advantage of this by using a system of phylogenetic classification. In contrast to the traditional Linnaean system of classification‚ phylogenetic classification names only clades. For example‚ a strictly Linnaean system of classification might place the birds and non-Avian dinosaurs into two separate groups. However‚ the phylogeny of these organisms reveals that the bird lineage actually

leaf. That is to say‚ all the light that comes from the sun gets absorbed into the leaf‚ but the green light bounces off‚ thus making the leaf appear‚ green. The green in leaves comes from a material called chlorophyll. Chlorophyll is where photosynthesis takes place‚ and there for it is very important to the health of a plant. Reduce humidity in your home. Sun-dry the used tea leaves and leave them in a damp corner to absorb excess moisture. Be sure to dry them outside your home‚ or you’ll just

Only in light can a green plant make food. Plants most also have clean air. Green plants take in carbon dioxide from air and use it during photosynthesis to make food. Dirty‚ smoggy air blocks sunlight that plants must have. Plants need water. Water is essential to all life on earth. No known organism can exist without
