Which two groups of organisms contain members that carry out photosynthesis?
fungi and plants
plants and algae
protists and fungi
animals and algae

Plants and algae

Explanation:

Algae belong to kingdom protoctista which comprise of the protozoans. The protozoa are heterotrophic taking in ready-made food. However, algae have chlorophyll which traps light and make their own food by photosynthesis. The plants belong to kingdom plantae. They all contain chlorophyll and make their own food through photosynthesis.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
