Duckweed as a nutrient thief and bioremediator Hypothesis: This experiment will evaluate duckweed and its ability to remove nutrients and toxins from water sources. Thus‚ duckweed will kill the organisms that require similar nutrients‚ yet aid the organisms that would otherwise die to toxins. Specifically‚ if one was to place Elodea plants in a tank with duckweed‚ then the Elodea will die due to the lack of nutrients from the duckweed having used the nutrients for its own benefits. Furthermore

The venus fly trap is a carnivorous plant. That means that it gets some of its nutrients from eating living things like insects and spiders. If you’ve never seen a venus flytrap before‚ they look like a flower with mouths at the ends of some of the leaves. The “mouths” look like they have teeth all the way around them and they are opened wide until they are ready to eat. The venus fly trap isn’t going to try to eat until its prey lands on it or moves across it two times. It waits because it doesn’t

spike. This permitted the seed to germinate properly without being disturbed by birds or any other animal that might eat the seeds. The control of planting seeds wit the seed drill was greatly improved that it saved seeds and allowed most of the plants to germinate at the same rate. This created increased crops and profits for the farmer. The results of the seed drill were greatly welcomed by most people. The growing population of the country sparked a new need for food and farmers. The trade

For example‚ a 20-20-10 fertilizer would contain 20 percent nitrogen‚ 20 percent phosphorus and 10 percent potassium. Secondary nutrients and trace elements are typically listed.

Introduction: All plants need water‚ carbon dioxide and sunlight as these are the main components needed for photosynthesis. The process of photosynthesis occurs in all plants‚ plants absorb sunlight through the leaves using the chlorophyll pigments in the leaf cells. The carbon dioxide diffuses through the stomata‚ under the leaf. The roots of the plants absorb the water from the soil and then the xylem will transport the water and nutrients upward to the leaves. As well as that the

Abiotic: non-living factors or components‚ e.g. soil‚ water‚ wind‚ etc… 2.1.2 Trophic level: is the position that an organism or a group of organisms in a community occupies in a food chain. 2.1.3 A food chain shows the flow of energy from one organism to the next. A food web is a complex network of interrelated food chains. Producers (autotrophs): manufacture their

zone affects the physical and the chemical properties of the water and largely influences the organisms affecting their feeding‚ metabolic rates and reproduction. It also affects how much oxygen can be dissolved in the water and how quickly the nutrients will be cycled through the water. Oxygen is better dissolved in cold water because gases are trapped by water molecules at colder temperatures. When temperatures rise‚ the molecules move around more‚ and gases‚ such as dissolved oxygen are able to

Introduction Ecosystem is similar to a community. It consists of species‚ living organisms and the abiotic factors‚ their habitat. Living organisms includes animals‚ plants‚ insects‚ micro-organisms. For their habitat‚ they are the non-living nature which are soil‚ sunlight‚ water‚ precipitation. There are two types of ecosystem. Terrestrial ecosystem which is on the land and aquatic ecosystem which is under the water. Over-breeding is the increase of offspring of a species to a excessive number

Mega 1 The Impact of Pseudoscience on Consumers Pseudoscience is known by many as false science. Many consumers are convinced by companies that sells these products provide instant cures that lead to a healthier lifestyle. These products are scientific theories that have little evidence to back up their scientific claims. The Internet‚ health food stores‚ magazines‚ and commercials are just a few ways that companies can target potential consumers to sell their products. Medical information searched
