Topical+Essential+Questions

1. What is the relationship between energy and matter? Matter needs energy to perform the different processes. Energy can transform matter (photosynthesis), and matter can store energy.

2. How is energy significant to biological system? Energy is needed to support the various living processes and systems, enabling the living organism to survive. Carry out life processes (respiration).

3. Can an organism survive without the exchange of matter with its environment? No. All organisms need to breathe and respire, thence, it is compulsory for them to exchange gas with the environment outside their bodies. E.g. photosynthesis

4. Are all matters living and all living organisms made of matter? Yes. Matter is defined as things with mass and volume, hence all living organisms are made of matter.

5. Can living organisms create and destroy energy? No. Energy cannot be created or destroyed, but it can exist in different forms of energy.

6. Can living organisms create and destroy matter? No.

Autotroph- plants Heterotroph- animals

Anabolism - built up of energy (photosynthesis) Catabolism - built down of energy (respiration)
