Best Answer

Algae obtain their food from photosynthesis . They absorb sunlight that gets to them and with a couple different processes they turn the sunlight into light energy which is converted into chemical energy which helps to make energy ( ATP ).With the ATP they can transform carbon - di

- oxide into glucose . Glucose is their food.

Which substance allows algae to harvest and use the energy from sunlight?

Some algae have chloroplasts and chlorophyll and obtain their energy through photosynthesis while some algae like euglena are both heterotrophic (decompose dead organic matter) and autotrophic (use photosynthesis) and can also obtain energy likewise. Hope I helped.


Abiotic needs of red algae?

one abiotic factor affecting the abundance and distribution of red algae (scientific name rhodophyta) is sunlight as red algae depends almost only on sunlight as it needs this to carry out photosynthesis to gain their energy. Without the required sunlight, red algae cannot perform photosynthesis, which means they won't have the energy they need and therefore will find it difficult to survive.
