The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995.. A study of the growth, movement, reproduction and survival of plants, it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth.
The existence of a global carrying capacity, limiting the amount of life that can live at once, is debated, as is the question of whether such a limit would also cap the number of species. While records of life in the sea show a logistic pattern of growth, life on land (insects, plants and tetrapods) shows an exponential rise in diversity. [10]
In the earliest known antagonistic relationships with plants, insects consume plant pollen and spores. [6] Since 300 million years ago, insects have been known to consume nectar and pollinate flowers. In the Mesozoic, between 200 and 150 million years ago, insects' feeding patterns started to diversify. [7]
At least three aspects of flowers appear to have coevolved between flowering plants and insects, because they involve communication between these organisms. Firstly, flowers communicate with their pollinators by scent; insects use this scent to determine how far away a flower is, to approach it, and to identify where to land and finally to feed.
The beautiful, ruffled flowers can look like a dress in motion. Some of these are very fragrant. The deep purple and white flowers of Oncidium "Sharry Baby" have the intoxicating smell of ...
One example of insect mutualism is the pollination of flowering plants by insects, a field of study known as anthecology. Primarily, various bee species work as pollinators of flowering plants, feeding on their nectar and in turn picking up their pollen and spreading it to other flowers. [ 28 ]

Carrion flowers attract flies and other carrion-feeding insects by their smell. [12] Orbea variegata illustrated.. Carrion flowers, including the enormous Amorphophallus titanum, [11] mimic the scent and appearance of rotting flesh to attract necrophagous (carrion-feeding) insects like flesh flies (Sarcophagidae), blowflies (Calliphoridae), house flies and some beetles (e.g., Dermestidae and ...
