Answer:
Higher biodiversity seems to be associated with a better response to disturbance events
Explanation:
Biodiversity means 'the variety of life'. Disturbance processes modify the environment and also affect demographic processes such as growth, recruitment, survivorship, etc., thereby producing changes in biodiversity. In an ecosystem, biodiversity contributes to its sustainability. In this regard, it has been shown that disturbance events are less important in species-rich ecosystems such as tropical wet forests compared to less rich ones (such as dry forests). The communities with higher biodiversity levels are known to be more productive in terms of biomass, and thus they seem to be more stable (and successful) to disturbance events.
Tiktaalik is a transitional fossil which shows how fish evolved into amphibians and reptiles. So the correct option is B.
What is Tiktaalik?
Tiktaalik is a direct ancestor of tetrapods or four-legged animals. It is an extinct fish-like animal and it lived on earth 380-385 million years ago (Devonian period).
The word Tiktaalik is derived from the <em>Inuktitut</em> language which loosely translates to large freshwater fish. This animal had characteristics of both fish and tetrapod and is therefore called the link between these two kinds of animals.
The characters resembling fish are gills and scales and the characters resembling tetrapods are rib bones, movable neck and lungs. There are characters that are a mix of both tetrapods and fish. These are bones and joints in limbs but fish-like fins instead of feet or hands.
