In Haiti, poor people are known to eat bonbon tè made from soil, salt, and vegetable shortening. These biscuits hold minimal nutritional value, but manage to keep the poor alive. [ 34 ] However, long-term consumption of the biscuits is reported to cause stomach pains and malnutrition, and is not recommended by doctors.
Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants. [11] Since some uninhabited land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration.
It was his last scientific book, and was published shortly before his death (see Darwin from Insectivorous Plants to Worms). Exploring earthworm behaviour and ecology, it continued the theme common throughout his work that gradual changes over long periods of time can lead to large and sometimes surprising consequences.

One example of primary succession takes place after a volcano has erupted. The lava flows into the ocean and hardens into new land. The resulting barren land is first colonized by pioneer organisms, like algae, which pave the way for later, less hardy plants, such as hardwood trees, by facilitating pedogenesis, especially through the biotic acceleration of weathering and the addition of ...
Waxworms are a commonly used food for many insectivorous animals and plants in captivity. These larvae are grown extensively for use as food for humans, as well as live food for terrarium pets and some pet birds, mostly due to their high fat content, their ease of breeding, and their ability to survive for weeks at low temperatures.
As local climates transition, locations that have long been conducive to one type of ecosystem can become more favorable for other ecosystem types. For example, warming in the Arctic has caused stress in North American boreal forests , [ 5 ] thus decreasing primary production and carbon uptake, while the same warmer temperatures have led to ...
