changed the atmosphere. High above Earth‚ the sun’s energy had converted much of the oxygen into a dense ozone layer‚ a shield against lethal doses of ultraviolet radiation. Until then‚ life had not ventured above the surface of water and mud. Algae were evolving at the water’s edge‚ and one group – probably the charophytes – gave rise to plants. Cooksonia‚ a simple branching plant a few centimeters tall‚ evolved by 430 million years ago. It took another 160 million years for the taller Psilophyton

Abstract This investigation examined the preferred habitat of the prawn Alope spinifrons for the purpose of keeping the prawn in optimum conditions in captivity. The survey took place on shoreline between Matapouri Bay and Wooleys ’ Bay on the Tutukaka Coast. A. spinifrons populations were surveyed‚ water chemistry‚ temperature and depth were noted as well as substrate type and flora and fauna sharing the area. A. spinifrons preferred sheltered rocky areas where there was good water circulation

INTERDEPENDENCE BETWEEN THE SPECIES INTERACTION BETWEEN PLANTS AND ANIMALS: Animals are depending upon plants for their food shelter and also for various things. ANIMALS HELP PLANTS IN DIFFERENT WAYS 1.Many animals are involved in the pollination in plants. 2.Fruits and seeds of many plants are dispersed by animals 3.Decomposers convert organic substances into inorganic substances so that plants can absorb them easily.

NAME: NABILAH HAMDIAH CLASS: 4K2 In the film that was shown to us by our Biology teacher‚ Miss Fairuz Adlidna‚ there were two different ecosystems that were being displayed‚ a marine one and a tigers’ habitat for the other. Based on my observation‚ I have decided to make a film review on the marine ecosystem. Through a documentary that was based in the United Kingdom‚ “INSIDE LIFE”‚ a young boy called Sam Wigfield was offered the opportunity to be a part of the shooting crew. His job was

Energy demand is increasing day by day owing to our dependency upon fossil fuels‚ which is a limited energy source and also poses negative effect on environment due to CO2 removal. Concerns about increased global energy demand‚ finite natural resources and environmental issues‚ are thus intensifying the search for sustainable‚ clean‚ renewable and eco-friendly alternatives to fossil fuels (Venkata mohan et al.‚ 2008). Renewable energy can be defined as energy that comes from constantly replenished

as phosphorus and nitrogen flowing into the natural water. Accumulation of the nutrients‚ particularly phosphorus in the water leads to excessive growth of algae population. Rapid growth of algae cover entire surface of the water and block the sunlight from entering‚ thus disrupt photosynthesis process of aquatic plant. As time passes‚ algae begin to die and decompose by bacteria‚ producing acidic byproducts which make the water acidic. Another factor is acid rain which mostly occurs due to human
