Essays on Decomposers

Which is a better choice at the grocery store: paper bag? Plastic bag? Or tissue bag? Explain your answer.The best choice at the grocery store is to bring a used bag. Paper bags, plastic bags, and tissue bags all have individual issues associated with their use. Paper bags come from a renewable source, and are biodegradable. Despite this, they require more energy to make and are less likely to be reused. Plastic bags are not biodegradable but consume less energy to be made than paper or tissue bags. Tissue bags are the highest energy consumptive option, but are more ...

Question 1

Binary mission in prokaryotes Mitosis and Meiosis in eukaryotes Question 2 The development of embryos as well as the growth and development of bodies. Important in asexual reproduction. Question 3 The term cell cycle refers to an ordered set of events leading to cell growth and division into two daughter cells.

Question 4

Interphase is a phase of the cell cycle characterized by the absence of cell division. During this phase, the cell obtain nutrients, the organelles duplicates, protein synthesis takes place, and cells duplicate its genetic material (its chromatids). The genetic material is located in the nuclei of ...

Q1) Distinguish between each of the following:

- Ecologist and environmentalist (give a Canadian example of each): An ecologist is a person who studies the complex relationships between living organisms and their surroundings. These surroundings can be living like human beings, plants, animals, etc. or non-living like the climate. They are concerned about maintaining the integrity of ecosystems as a whole. Ecology is a very vast field and covers areas like food chains, biomes, etc. Pierre Dansereau is a well-known Canadian ecologist. Environmentalists, on the other hand, are concerned with protecting the environment from harmful human actions. David Suzuki is a famous Canadian environmentalist.

- Primary Succession and Secondary Succession: Succession ...

Producers are the organisms that capture the Sun’s energy and convert this energy into a usable form of energy for themselves or others. Examples of producers in grassland include shrubs, trees, lichens, mosses and grass, etc. Consumers are the organisms having no way of capturing the Sun’s energy and rely on energy gained from producers or other consumers. Examples of consumers in grassland include elks, black bear, Western rattlesnake, red-tailed hawk, etc. Decomposers are the organisms that break the organic layer in the soil in order to provide nutrients to the producers. Examples of decomposers in grassland include ...

All the three major categories of organisms viz. Producers, consumers and decomposers are abundantly present in a tropical forest ecosystem. Primary producers are the autotrophs that can capture the light energy and manufacture their own food. The major producer plants in a tropical forest are ferns, bananas, vines, epiphytes and grasses. Consumers are the heterotrophs that cannot synthesize their own food and are dependent on other organisms. They are further classified into primary, secondary and tertiary consumers. The primary consumers include herbivore animals, birds and insects including macay, parrot, sloth, bats, etc. These organisms directly feed on green plants (producers). Primary ...

Introduction

Everglades evolved from overflow from Lake Okeechobee after thousands of years of intense torrential rainfall. From lakes shores of Florida bay and Gulf Mexico, this vast marsh extends southwestwards. Stephanie Moller. (2008). At the southern tip of Florida Peninsula, the marsh begins and continues to extend northwards towards Lake Okeechobee, and it lies in a shallow limestone basin. Several streams like Miami drain the area without any river flowing into the basin. The Everglades are an excellent wetland located at the margins of the tropics. This magnificent ecosystem provides shelter to a variety of animals, birds and fish. This unique ...

Describe the process of transpiration in vascular plants

Similar to other living organisms, plants possess the capacity to regulate their internal atmosphere. Vascular plants scientifically known as tracheophytes possess conducting tissue which offers independence from a wet or dry environment. These plants have a multifaceted structure of tubes known as the vascular system to carry water and other important solutes. Phloem moves all through the plant as it conveys biological solutes in aqueous states in all direction. Reliant on the period and the plant's requirements, phloem can even alter its flow course.

Xylem originates at the root running via the stems and concludes at small pores known as stomata ...
