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

Corn rootworms are currently a pest for over one hundred different host plants through out the country. Economically speaking‚ they do the most damage to corn crops in the Corn Belt. There are three main different types of Corn rootworm: Northern corn rootworm‚ Western corn rootworm‚ and Southern corn rootworm. They all have their own unique way to reproduce and affect the farmer’s crops. Northern corn rootworm has a unique life cycle. The female insects lay eggs in late August. Those eggs

1. Define the following terms: Xerophytic = A plant adapted to living in a dry arid habitat; a desert plant Pyrophytic = plants adapted to tolerate fire Deciduous = Loss of leaves seasonally Perennial = lives more than 2 years Dormant = A condition of significantly reduced activity with very less or no growth. All physiological activities‚ like photosynthesis‚ are minimal or non-existent. 2. Research specific adaptations/plants which are typical of the Savanna. Your notes should

thing on the earth. And then there is the oxygen cycle. The cycle where oxygen is used‚ broken apart by animals. It is then restored to the globe when it is remade in the respiration cycle of plants. Micronutrient and Macronutrients interact or move along with theses cycles‚ supplying nourishment to the plants and animals that rely on these cycles for their very life. Both of the nutrients are necessary for health and life‚ but each one has a varied role. Micronutrients such as vitamins C and B

Georgia is a mountainous country that is surrounded by Azerbaijan in the east‚ the Black Sea in the west‚ the Russian Federation in the north and the Armenia in the south forming a 330km-long coastline. The climatic condition of Georgia varies among the six states` land regions that are well defined by the four seasons: A warm summer that is characterized by an average temperature of around 800C with an added advantage of the Indian summer that stretches into October. It also has an autumn brisk

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

Paramecium living in the intestines of termites breaks down the cellulose walls of wood fibers releasing proteins that are absorbed by the termites’ digestive system. Paramecium benefit by having an environment to thrive and they ingest the wood fibers for their own nutrition as well. 2. c. An important ecological effect
