Answer:
During primary succession on land, fungi and lichen are the most common pioneer species. They break down minerals in the rock to form soil, which allow subsequent communities to colonize the area .

Answer:
Photosynthesis converts light energy to chemical energy in plants and cellular respiration converts biochemical energy from nutrients in organisms.
Explanation:
- Photosynthesis is a process that occurs in green plant that synthesizes food for plants from the use of sunlight and series of chemical reactions.
- Similarly cellular respiration also does the same but it uses nutrients consumed from the body to produce energy for different cellular activities.
- Cellular respiration converts energy into ATP form in organisms.
- Photosynthesis uses sunlight where as cellular respiration needs oxygen to prepare food and energy.
Answer:
Biotechnology is used to increase the disease resistance of sharks by modifying their skins
Explanation:
Through the use of biotechnology, bio engineers have found a way of producing artificial sharkskin which are resistant to bacteria. This sharkskin do not allow bacteria to grow on it and also produce chemicals used in manufacturing antibiotics. Also with the help of biotechnology, the skin of sharks can be made to resist most disease by attaching a device on the shark skin.

Research is necessary to gather data that is used to formulate a hypothesis and to create the experiment.
Identify a problem. The problem is the question you are trying to answer. Without a problem, there is no reason for experimentation.
Formulate a hypothesis. The hypothesis is a statement, based on your research, that is intended to provide a solution to the problem. The hypothesis is what you are trying to prove or disprove.
Conduct your experiment to prove the hypothesis. A controlled science experiment is setup to test whether a variable has a direct causal relationship on another.
Identify your independent and dependent variables. The independent variable is commonly known as the cause, while the dependent variable is the effect. For example, in the statement A causes B, A is the independent variable and B is the dependent. A controlled scientific experiment can only measure one variable at a time. If more than one variable is manipulated, it is impossible to say for certain which caused the end result and the experiment is invalidated.
Do not alter your hypothesis midway through the experiment. The setup of a controlled scientific experiment must be constant. You can not make changes once you have begun, even if the results you are getting do not seem to support your original hypothesis. When you change your hypothesis, you change the entire experiment and you must begin again.
Do not be upset if your results are not what you expect. Some of the greatest scientific advances have come from experiments that disproved the original hypothesis.
Start over again with a new hypothesis or find new variables to manipulate. Scientific advancement is a painstakingly slow process and scientists often spend years and even an entire lifetime working on the same problem.
