lichens are called pioneer organisms because they are the first type of organisms that started to live in a certain forest or such. For example, If a volcanic island were to appear in the middle of the ocean. It is devoid of life at first. Certain organisms will land on the island either by washing up on the volcanic ash or land on it after being carried by the wind currents. One of these organisms would be a lichen. Lichens are considered pioneer because they will begin to destroy the rock and ash producing soil. They can survive because a lichen is a mutualistic relationship between a fungus and an algae. Once these lichens have done their work other organisms will appear, bacteria, algae, various grasses, etc. This is called ecological succession.
In ecology we use several levels of organization to describe the organisms and habitats of an ecosystem. The level of organization that refers only to members of a certain species in a certain area is the population.
Living organisms depend on other living organisms as food sources. AN overpopulation of a certain living organism or a decrease in a population of an organisms may unstable the other organisms that depend on it for food.
an organism is 1 living species and species are things that live in a certain area
BECAUSE
Temperature regulating mechanisms are very important in organisms. This is because cells in organisms can only survive and be productive in certain temperatures.
its so important because certain organisms have economic value
yes, accidental contact with chemicals..affects farmers health. because og the reaction in certain components in chemicals..
because their brains are different
Because the cash crops that were sold which needed certain equipment in which farmers couldn't afford.
Because a desert is dry and only certain animals can live their where as a rainforest has rain and sunlight and food that organisms can live with
because its more likely to survive
Yes, infact the government might tax farmers for there animals because they fart.
Because the cash crops that were sold which needed certain equipment in which farmers couldn't afford.
In addition to exposure to sufficient quantities of causative organisms, certain conditions may make an individual more likely to become ill with pneumonia.
This is actually a fallacy. Fair trade will improve farmers lifes for those farmers that are paid wages that meet certain standards however those farmers that are not paid standard fair wages can suffer because they will lose business and make less.
