Example: rocky seashore – Algae of the sub tidal zone: This zone is the least stressful zone‚ and it lies below the normal watermark. The most common algae in this zone are the large brown kelps‚ which are strongly attached to rocks and rocky formations. They have long fronds that float‚ whilst some have air filled bladders that help them float‚ and that are photosynthetic‚ and they form the canopy of a marine forest. Organisms of the intertidal zone: Brown algae Hormosira banksia is the most

Therefore Coral reefs live in a relationship with the millions of microscopic algae called zooxanthellae. Coral reef provides nutrients and protection to zooxanthellae. Algae helps coral to grow faster by providing it with photosynthesis using the sunlight to convert these into more complex nutrients like sugar‚ which the polyps then eat too. Also the zooxanthellae gives the coral it colours‚ the coral tissues are clear and these algae come in all kinds of different colours‚ which is why coral reefs are normally

WATER POLLUTION IN CHINA River like blood in Roxian‚ Guangxi About one third of the industrial waste water and more than 90 percent of household sewage in China is released into rivers and lakes without being treated. Nearly 80 percent of China’s cities (278 of them) have no sewage treatment facilities and few have plans to build any and underground water supplies in 90 percent of the cites are contaminated. Water shortages and water pollution in China are such a problem that the World Bank

Introduction This report deals with the study of an ecosystem group and a major functional role within it. The components of the role and other factors such as relationships within the ecosystem are discussed along with quantitative data and examples. The ecosystem group chosen is a local‚ coastal ecosystem called the Barker Inlet – St Kilda Aquatic Reserve and the Torrens Island Conservation Park. Together we have termed them the Barker Inlet Mangrove Ecosystem which is situated approximately

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.

AGRICULTURE Agriculture is the production of food and goods through farming and forestry . Agriculture was the key development that led to the rise of human civilization‚ with the husbandry of domesticated animals and plants creating food surpluses that enabled the development of more densely populated and stratified societies. The study of agriculture is known as agricultural science. Agriculture encompasses a wide variety of specialties and techniques‚ including ways to expand the lands
