What type of fertilizer includes animal manure and compost made with plant or animal products?

The correct choice is organic fertilizer because it is derived from natural sources such as animal manure and compost made from plant or animal products. Organic fertilizers are rich in nutrients and improve soil health by enhancing its biological activity. They provide a slow release of nutrients, which is beneficial for sustaining plant growth over time while also promoting ecological balance.

In contrast, inorganic fertilizers are typically manufactured synthetically and do not contain organic matter. Synthetic fertilizers are chemically formulated and can provide nutrients quickly but may lead to issues such as nutrient runoff and soil degradation when used excessively. Chemical fertilizers is a broader term that often overlaps with synthetic but can also refer to any fertilizer that involves chemical components, not necessarily derived from natural sources.
