which of these is not an enviromental effect of farming. habitat loss. soil erosion.flooding. incerased carbon dioxide levels
harkovskaia [24]
Let's go through these one by one:

- Habitat loss is an environmental effect of farming. When vegetation is torn up to make room for a farm, the organisms living in those plants and trees are losing their homes.

- Soil erosion is an environmental effect of farming. When the vegetation native to an area is torn up and replace with domesticated crops, the topsoil is more likely to be blown away. This is because native plants will typically have longer root systems, which hold the soil down better. Erosion can also be an issue if the crops aren't planted in ideal places or are organized in the wrong way.

- Flooding is an environmental effect of farming. This can be caused by two main ways. Either the erosion that occurs doesn't leave enough soil to absorb water, leading to a flooding on the soil, or the irrigation and drainage systems have been improperly set up.

- Increased carbon dioxide (CO₂) is not an effect of farming. While there may be deforestation happening that would decrease the vegetation density of the area, a farm will have crops. These crops are just like the native vegetation, in that they will perform photosynthesis. This effectively turns CO₂ (and water and light) into oxygen and glucose (sugar). So, the overall CO₂ level will not increase.

The answer to your question in "Increased Carbon Dioxide levels".

They are currently represented by the amphioxes. Cephalocords are the group of invertebrates that is most related to vertebrates.

The body of the cephalocordates is composed of longitudinal (horizontal) muscles that are divided by blocks called myotomes. The notochord holds in adults giving a stronger structure to the body.
