Protists Protists are a very large‚ diverse group of organisms‚ including the plant-like protists (algae)‚ fungi-like protists‚ and the animal-like protists (protozoans). They are all eukaryotic‚ and most are unicellular. Traditional taxonomy of protists (Kingdom Protista) did not accurately represent evolutionary relationships‚ so the classification of this group is unsettled. Modern taxonomy has rearranged the group formerly known as Kingdom Protista‚ separating the different types of organisms

How do limiting factors affect the rate of photosynthesis? Rate is the measurement of an amount of product or time. In the case of the rate of photosynthesis‚ it is measuring the gain of mass or growth over time. If the plant is an aquatic one that grows in water the rate of photosynthesis can be measured by counting oxygen bubbles or the volume of gas produced in a measured time period. A limiting factor is something that is present in the environment that has a short supply and because of that

While the Gardens strives to mimic a natural environment by housing a wide variety of plant species‚ it would still not be a natural environment. 2.2 Education-based 2.2.1 Ecology Awareness Gardens provide an excellent edutainment opportunity for the visitors.

It feeds on animal and plant material by using it’s whiskers. * Fossil- Crinoid‚ June 16‚ 1989. It is the mineralization of an animal which has a plant-like appearance‚ so it is known as the “sea lily.” * Mineral- Galena‚ July 21‚ 1967. It is the major source of lead ore. It is dark gray in color and breaks into small cubes. *

required in plant growth. Nitrogen and phosphorous were tested separately‚ where the concentration of each was increased while the other remained constant. The results showed a positive increase in algal growth rate in the phosphorous samples and a negative relationship with increased nitrogen levels. In this way‚ phosphorous acted as the more significant nutrient in algal growth and should be controlled to prevent eutrophication. I. Introduction Several nutrients are required for plants to grow

Jade Woodcock Introduction “A Pond is commonly described by limnologists as a quiet body of water so shallow that rooted plants grow completely across it. Its water temperature is fairly uniform from the top to bottom and tends to change with air temperature. There is little wave action; and the bottom is usually covered with mud. Typically‚ plants grow all along the shore. The amount of dissolved oxygen may vary greatly in a 24 hour period.” (Pond Life 2001) There are several environmental

FOOD CHAINS and FOOD WEBS There are two types of feeding relationships: autotrophic and heterotrophic. Autotrophic organisms make their own food by the process of photosynthesis e.g. plants. Heterotrophic organisms cannot make their own food (i.e. cannot carry out photosynthesis)‚ therefore must eat other organisms to get their nutrients e.g. animals. A food chain is the feeding relationship among organisms or the series of living organisms that eat each other. A food chain shows the transfer

photo-synthesis. They are similar to higher plants‚ but they lack many of the distinct organs that you will find in a higher plant. The higher plants are believed to have evolved from algae‚ and algae are believed to have gotten their capacity for photosynthesis from cyanobacteria. Algae can be unicellular as well as multi-cellular. Large and complex forms found in the ocean are commonly referred to as seaweed and can look very similar to higher plants. Algae are voluntarily and involuntarily kept

A biome‚ also known as life zones‚ consists of all plants‚ animals‚ and other organisms‚ as well the physical environment in a particular area. A biome is characterized by its’ plant life‚ climate‚ and location. The climate and physical features determine the boundaries of a biome. A biome is made up of many different ecosystems. The ecosystems tend to have the same pants and animals as neighboring biomes around the boundaries. The major biomes are the tundra‚ taiga‚ tropical rain forest‚ temperate
