The variety of life on Earth, its biological diversity is commonly referred to as biodiversity.
The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse earth.
Why is Biodiversity Important?
Biodiversity boosts ecosystem productivity where each species has an important role to play. It means we maintain:-
Plants:- A greater variety of crops to feed us
Animals:-Species diversity maintains natural sustainability for all life forms
Ecosystems:- that can better withstand and recover from a variety of disasters.
When we destroy or reduce habitats, the chances for interaction from species with a large gene pool decreases.
Biodiversity whether it be diversity in genes, species or ecosystems benefits everyone. Here are some examples:-
Protection of water resources
Soils formation and protection
Nutrient storage and recycling
Sustaining the diversity of our planet makes economic sense.
And another thing…
Pollinators are essential for continued plant growth in the wild and the most common plant pollinators, are bees and butterflies. The transfer of plant pollen to a female species of plant or the female part of the plant enables fertilization, leading to the growth of new plants.
When bees collect nectar and pollen from the flower of a plant, some pollen from the stamens, the male part of the flower, sticks to the hairs on its body and gets transferred to the next flower that it visits.
The second most productive pollinators are butterflies. Although they visit flowers often, they lack the specialized pollen-carrying structures so that pollen doesn’t stick to their bodies as much as it does to bees.
Some wasps do visit flowers. Although generally thought to be less efficient pollinators than bees. This is because wasps lack the body hairs that bees have to carry pollen and so are not as well equipped for carting pollen from flower to flower.
Most moths are nocturnal. These night-flying pollinators commonly pollinate white, fragrant flowers, such as jasmine.
Many flies like to feed on the nectar in flowers, whilst doing so they provide pollination services to the plants they visit. Nearly half of the 150 fly families visit flowers. Flies are particularly important pollinators in places there are fewer bees, such as alpine or arctic habitats.
No bigger than the size of pinheads, midges are often the only creatures that can work their way into some of the tiniest flowers in order to pollinate. They are most active in this way at dusk and at dawn.
Mosquitoes are best known for feeding on blood, but those are only the female mosquitoes. And, this only happens when she has eggs to lay. The mosquito’s favourite food is actually nectar. Any time an insect drinks nectar, there is a good chance it is going to collect pollen.
Most beetles that visit flowers do not sip nectar. Beetles often chew and consume parts of the plant they pollinate and leave their droppings behind. For this reason, beetles are referred to as mess-and-soil pollinators.
Pollination by ants is not as common because most pollinators can fly, enabling them to distribute pollen grains over a wider area. This type of pollination promotes genetic diversity across the plants they visit. Since ants walk from flower to flower, their pollen exchange is limited to a small number of plants.
