Answer:
reduction in potential medicines
decreased food supply
Explanation:
The direct impacts of a decline in angiosperm biodiversity include a decrease in accessible medicines and food sources.
Angiosperm biodiversity, or flowering plants, serve as essential food sources for numerous living organisms, including humans, clearly demonstrated in human agricultural practices. Various consumer categories within ecosystems rely heavily on flowering plants for sustenance, whether directly or indirectly.
Moreover, they also provide medicinal resources. For instance, chloroquine, a principal treatment for malaria, is derived from the flowering plant Chinchona pubescens.
Many species of flowering plants remain uncatalogued in the wild, holding potential for future food and medicinal applications.
Therefore, a loss in flowering plant diversity will directly lead to a reduction in available food and medicine.
With the provided diagram above, I think the answer is OXYGEN, which is the first option. The gas anticipated to be present in the highest concentration within the bubbles is oxygen; since it’s a plant sample, it’s expected to emit oxygen and absorb carbon dioxide. I hope this answer aids you.
