Final answer:
A decrease in photosynthetic organisms from deforestation has a negative impact on the planet by increasing carbon dioxide levels, contributing to climate change, causing habitat loss, soil erosion, and a decrease in biodiversity.
Step-by-step explanation:
When there is a decrease in photosynthetic organisms from deforestation, it has a negative impact on the planet. This is because photosynthetic organisms, such as trees, play a crucial role in reducing carbon dioxide levels by absorbing it during photosynthesis. With fewer photosynthetic organisms, carbon dioxide levels can rise, contributing to climate change and global warming.
Furthermore, the decrease in photosynthetic organisms can also lead to habitat loss for various species, soil erosion, and a decrease in biodiversity. Trees and other plants help stabilize the soil and prevent erosion, so their removal can have detrimental effects on the environment.
In conclusion, a decrease in photosynthetic organisms from deforestation reduces the ability to absorb carbon dioxide, contributes to habitat loss, soil erosion, and a decrease in biodiversity, and overall has a negative impact on the planet.
