The interconnectedness of various scientific phenomena is evident through the discussion of pests, the role of the sun in photosynthesis, and the utilization of solar energy. Pests, which are detrimental to crops and livestock, are often controlled using pesticides, chemical compounds specifically designed for this purpose.
A destructive insect or other animal that attacks crops, food, livestock, etc.
Pesticides are chemical compounds that are used to kill pests
Pesticides are chemicals that we humans use to kill pests we don't want.

Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun.
If there is no light there would be less energy in the world that humans can use.
Producing Light energy from solar panels.
Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. Carbon dioxide, water and light are all needed for photosynthesis to take place.
The sun is the ball of fire in the sky that the Earth goes round, and that gives us heat and light.
Plants need light from the sun to do photosynthesis and humans need oxygen and food from the plants.

Without these we wouldn't know what is an organism is like
Physical Properties
Chemical properties cannot be determined by touching or viewing a sample.
Chemical Properties
Physical properties are any properties of matter which can be perceived or observed without changing the chemical identity of the sample.
