εbc, where ε is the molar absorptivity of the absorbing species, b is the path length, and c is the concentration of the absorbing species.
Are hares endangered in the UK?
The brown hare has a Species Action Plan under the UK Biodiversity Action Plan, which aims to expand existing populations. However, the brown hare has minimal legal protection because it is considered a game species and can be shot throughout the year, including through their breeding season.
Why is it important to save the spotted owl?
First, saving the spotted owl will save an entire ecosystem on which plants, other animals, and humans depend. The spotted owl is considered an indicator species — a gauge of the health of the ecosystem that provides its habitat.

Extinctions have been a natural part of our planet’s evolutionary history. More than 99% of the four billion species that have evolved on Earth are now gone. At least 900 species have gone extinct in the last five centuries.
Why are hares going extinct?
The hare population is believed to have been more or less stable since the 1990s. The low number of hares in some parts of the country is largely due to habitat loss and predation.

Is extinction natural or manmade?
Extinction is a natural phenomenon: After all, more than 90 percent of all organisms that have ever lived on Earth aren’t alive today. But humans have made it worse, accelerating natural extinction rates due to our role in habitat loss, climate change, invasive species, disease, overfishing, and hunting.
What was the worst mass extinction in Earth’s history?

What are tigers biggest threats to extinction?
The main threats to tiger populations today are habitat loss/fragmentation and poaching. Habitat Loss and fragmentation occurs when land is modified for agricultural purposes, logging, and land conversion for grazing domestic animals. The rapidly growing human population has reduced the number of viable tiger habitats.
