Everyone’s body is made of the same basic stuff. All living things, large or small, plant or animal, are made up of cells. Most living things are made up of one cell and they are called unicellular organisms. Many other living things are made up of a large number of cells that form a larger plant or animal. These living things are known as multicellular organisms. Water makes up about two thirds of the weight of cells.
Cells are very small; most cells can only be seen through a microscope. Cells are the smallest living units that are capable of reproducing themselves. Each cell in your body was made from an already existing cell. All plants and animals are made up of cells. In this article, we will talk about the cells that make up You.
pre All the parts of your body are made up of cells. There is no such thing as a typical cell. Your body has many different kinds of cells. Though they might look different under a microscope, most cells have chemical and structural features in common. In humans, there are about 200 different types of cells, and within these cells there are about 20 different types of structures or organelles.
Answer: D. Competitive exclusion
Explanation:
This is because the competitive exclusion theory states that two organisms that compete for the same resource can't co exist. It doesn't effect the carrying capacity.
Cocoa is the dried and fully fermented fatty seed of the cacao tree from which chocolate is made.

Climate
Cocoa can be grown up to 300 m above mean sea level. It requires a minimum of 90-100 mm rainfall per month with an annual rainfall of 1500-2000 mm. The plants need equitable climate with well distributed rainfall. If dry periods are prolonged, irrigation scheduling is necessary. The temperature range of 15°-39°C with optimum of 25°C is considered ideal.
Soil
Cocoa requires deep and well drained soils. Poorly drained soil affects growth of plants. Majority of area under Cocoa cultivation is on clay loam and sandy loam soil. It grows well in the pH range of 6.5 to 7.0.
Shade requirement
Cocoa was evolved as an under-storey crop in the Amazonian forests. Thus commercial cultivation of cocoa can be taken up in plantations where 50 per cent of light is ideally available. In India, coconut and arecanut gardens are suited best for cultivating Cocoa. Under arecanut 30-50% of sunlight penetrates through their canopy which can be intercepted by cocoa.
