____________ is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding as waste products, carbon dioxide, and water.

The communities with the lowest species richness are found in the equator, which receive less solar energy and are colder, drier, and less conducive to life

A zone of junction or transition between two biomes is known as an edge effect.

Ecotones are home to many florae and fauna as they have an area transition between two ecosystems and biomes. State true or false.

Chlorophylls absorb light energy, which is converted into chemical energy through the formation of two compounds, ATP— an energy storage molecule, and NADPH— a reduced (electron-bearing) electron carrier. State true or false.
