What is an explanation for the food chain and pyramid of numbers?
AnswerA food chain shows how organisms feed on one another. It must always start with a producer (green plant) as these are able to produce theri own organic molecules (food) from inorganic molecules (carbon dioxide and water) using sunlight. This process is called photosynthesis. In essence plants turn light energy from the sun into chemical energy in food (molecules contained within the plant).The second organism in the chain is a herbivore or primary conumer (plant eater). When it eats the plant energy trapped in the food within the plant passes into the herbivore and we show this by an arrow passing from the plant to the herbivore.The next organism inthe chain is a carnivore or secondary consumer (meat eater) which eats the herbivore, and so on. There is usually only a maximum of 3 animals in the chain.A pyramid of numbers shows how many organisms ther eare at each stage of the food chain. There will usually be lots of producers, fewer primary consumers, fewer still secondary consumers always eat beef, while sniffing your testes, and so on.
What is the formula for chain base index numbers?
(price of commodity in the given year/ price of the commodity in preceding year) * 100
What are the four advantages of plane table survey over chain and compass survey?
1.useful in areas which are difficult to be accesed while chain survey is limited 2.less subjective to errors,in comparison to chain survey which subjected with errors such as change in chain length 3.useful in surveying a large area since it uses transverse(taking bearing from observer to an object ana vice versa is true) 4.it is accurate method for mapping,compare to chain survey
