More specific to an agroecological context, high…[Read more]

The first trophic level, that of the primary producers (or autotrophs), includes native grasses, all crops, weeds, and trees. The second level, that of the primary con…[Read more]
Describe the levels of organization in your agro-ecosystem. Why is an agro-ecosystem more complex than multiple communities?
The first level of organization in my agro-ecosystem is organism (or microorganism). There exist bacteria, insects, chickens, dogs, and people, among others. Each individual is an organism (or microorganism). The next level…[Read more]
