Individual plants and animals could not exist by its self on earth. All organisms need other organisms for survival. An ecosystem is a community of living organisms. An ecosystem maintains an important balance in order for all organisms within the ecosystem to survive. The balance involves carbon‚ food‚ nitrogen‚ oxygen and water. The sun supplies the energy needed by ecosystems. Plants absorb the energy and use photosynthesis to convert it to sugar. There are nutrients in the air‚ soil and water

Distinguish between the strategies used by autotrophs and heterotrophs to obtain free energy for cellular processes. In other words‚ how and in what form does each capture and store that energy? 2. Explain how photosynthesis differs in eukaryotic organisms (with organelles such as chloroplasts) and in prokaryotic organisms (single-celled‚ no organelles). 3. How does a metabolic

Fern is a flowerless plant that has feathery or leafy fronds and reproduces by spores released from the undersides of the fronds. Ferns have a vascular system for the transport of water and nutrients. *Characteristics of Seedless and Vascular Plants: Includes: ferns‚ club mosses‚ and horsetails Have vascular tissue They are able to grow bigger and taller Within vascular plants is the phloem‚ the vessel that transports food‚ and the xylem‚ which transports water Vascular plants actually live in both

understanding of diffusion and osmosis‚ we examine multiple experiments to show diffusion and osmosis in animal cell‚ plant cell and synthetic cell. In our first experiment‚ we weight a decalcified chicken egg and place 10% NaCl concentration. At every fifteen minutes intervals‚ we weight the egg and record that the weight decreases. In our second experiment‚ we use three slices of aquatic plant Elodea and add pond water one leaf‚ distilled water for the second and 20% NaCl for the third‚ then observe the

Delgado‚ Karina Professor Tuscano NR 2 TTH AM 27 January 2015 Tundra Biomes In the world there are about twelve biomes. The major biomes include deserts‚ forests‚ grasslands‚ tundra and several aquatic environments. A biome is large geographical area with special plants and animal groups and they are adapted to that type of environment. The Tundra biome is the coldest biome of the many biomes. It is separated into two types which are the arctic and alpine. The following information was gathered

for Brassica rapa is field mustard and a type of plant is a cabbage. The plant was grown in solutions of pH 3 and 5.6 and the control was a solution of pH 7. This was done over 3 weeks and the plants were measured every day at the same time. The results of growth from day 4 to day 10 were recorded and they show that the plant grew the most in the pH of 5.6 at first but by the 10th day‚ the plant in the solution of pH 7 had grown the most and the plant in the pH 5.6 solution survived and was not far

classification of organisms. - He classified plants into trees‚ shrubs & herbs and animals into two groups‚ those which had red blood and those that did not. Two-kingdom classification - In Linnaeus’ time Two Kingdom classification (Kingdom Plantae & Kingdom Animalia) was developed. Drawbacks of 2-kingdom classification Prokaryotes (Bacteria‚ cyanobacteria) and eukaryotes (fungi‚ mosses‚ ferns‚ gymnosperms and angiosperms) were included under ‘Plants’. It is based on the presence of cell

Photosynthetic organisms‚ including plants‚ algae‚ and some photosynthetic bacteria‚ efficiently utilize the energy from the sun to convert water and CO2 from the air into biomass. It emphasized the use of photosynthetic organisms from aquatic environments‚ especially species that grow in environments unsuitable for crop production. Early in the project‚ macro algae‚ microalgae‚ and emergent were investigated for their ability to make lipids (as a feedstock for liquid fuel or chemical production)
