This planet underwent massive change in the environment million years ago to enable living organisms to thrive and survive in it. From single simple microorganisms, Earth’s environment allowed these organisms to evolve into a more complex and diverse organisms. What’s In On your answer sheet, list down five important biological factors that you need in order to live. From your list, select the top three most important factors for you. Explain your answer. Notes to the Teacher As facilitator kindly asks the learner to share the insights, he/she has gained during his/her exchange or consultation of experiences or ideas with his/her peers. 4 CO_Q1_ESS SHS Module 1  What’s New Earth’s environment is conducive to different life forms.

In its early formation, life was not possible because the environment did not permit it. However, as time went by, life flourished from microorganisms into a more complex organism. The presence of life on Earth was made possible due to the following factors: 1. Temperature. It influences how quickly atoms, molecules or organisms move. Low temperature slows down chemical reaction and produces ice that makes liquid water unavailable. High temperature can cause break down of important biological molecules. In Earth’s condition, temperature is just right to support life. 2. Water. It is one of the important ingredients in the different biological processes. Absence of this will interfere reactions necessary for life. However, solid form of this will also hinder living organisms to use it. Water on Earth has different forms. It is solid (ice) in the two poles and liquid along the equator which allows living organisms to consume it. 3. Atmosphere. It provides significant insulation or shielding from the sun and impact of small to medium size meteorites. Greenhouse gases like carbon dioxide (CO2) and methane (CH4) trap heat and protects our planet from freezing. Moreover, ozone (O3) layer shields the Earth’s surface from harmful UV radiation. Atmosphere also provides chemicals needed for life, such as nitrogen and carbon dioxide. The size of the planet and its distance from the sun affects its ability to hold significant amount of atmosphere. Earth has a right size and distance from the sun that permits it to have a right amount of atmosphere. The presence of gravity also helps in sustaining its atmosphere. 4. Energy. Earth has available energy- rich sunlight to support life. Living organisms like plants and photosynthetic bacteria use light as the source of their energy. Some chemosynthetic organisms rely on chemical energy to support various biological processes. 6 CO_Q1_ESS SHS Module 1  Earth is at right position from the sun that enables it to harness enough amount of sunlight. 5. Nutrients. It is an essential factor used to build and maintain organism’s body structure. Insufficient or absence of nutrients can impede synthesis of the different biological molecules. In our planet, there are processes that recycle nutrients. Water, carbon and oxygen, phosphate and nitrogen cycles are some of the examples. Volcanism also helps in cycling the nutrients. What’s More Write T if the statement is correct but if it is false, change the underlined word or group of words to make the whole statement true. Write your answer on your answer sheet. _________________1. Low temperature slows down chemical reactions among living organisms. _________________ 2.
