Answer and Explanation :
Plants and algae comprise the lowest level of the trophic system. Called primary producers or autotrophs, plants and other organisms create their own food using photosynthesis.
Furthermore Each organism in an ecosystem occupies a specific trophic level or position in the food chain or web. Producers, who make their own food using photosynthesis or chemo-synthesis, make up the bottom of the trophic pyramid
Answer:
The preferable words for the fill in the blanks will be -
Aragonite, calcite
Explanation:
- Biogenic minerals are minerals produced by living organisms. Two commonly seen biogenic minerals are <u>aragonite</u>, which is often produced by coral and other invertebrates, and <u>calcite</u>, which often makes up the shell material of mollusks such as clams.
- Biogenic minerals are the mineral substances that are produced by geologic processes. For living organisms, it is their most commonly produced byproduct.
- E.g; vertebral bones, shells of Oyster, mussel, and clam (aragonite), etc.
Answer:
A. Species X and Y share a greater number of homologies with each other than either does with species Z.
Explanation:
In taxonomy, living organisms are placed into groups according to their similarities.
Genus is a classification group above of species. It consists of species that are closely related.
For the species X and Y to be placed in the same genus, they must be sharing a greater number of similarities or homologies compared to species Z.
Species Z does not have greater similarity with either Species X or species Y
