A significant reduction in water levels in a pond, possibly due to drought or sediment buildup, would likely lead to terrestrial succession. As the pond dries up, the exposed areas would allow for the establishment of wetland and then upland plant species, gradually transforming the habitat from aquatic to terrestrial. This process would encourage the colonization of various terrestrial organisms, leading to a shift in the ecosystem dynamics over time.
An increase in sedimentation or a decrease in water levels would likely lead to terrestrial succession in a pond, as these changes can provide more favorable conditions for terrestrial plant growth. This would result in the gradual transformation of the pond into a terrestrial ecosystem.
A pond that is shallow and gradually fills in with sediment and organic material is most likely to lead to terrestrial succession. As aquatic plants and algae establish, they contribute to sediment accumulation, eventually allowing for the growth of wetland plants. Over time, this progression can lead to the development of a marsh or swamp, and eventually transition to dry land ecosystems such as grasslands or forests. In contrast, deeper ponds are less likely to undergo significant terrestrial succession.

If plants had not evolved to live on land, it is likely that terrestrial ecosystems would have remained dominated by non-plant organisms such as fungi, bacteria, and algae. This would have drastically altered the development of terrestrial ecosystems and likely impacted the evolution of animals that rely on plants for food and habitat.

Yes, pioneer organisms are essential for terrestrial ecological succession as they are the first species to colonize barren or disturbed environments. These organisms, such as lichens and mosses, help to break down rocks and contribute organic matter to the soil, facilitating nutrient accumulation. This process allows for the establishment of more complex plant species over time, leading to increased biodiversity and the development of stable ecosystems. Without pioneers, succession would be significantly slower or may not occur at all.
The inner or terrestrial planet that we could most likely live on is Earth. Mars would be a far distant second.
