Most carnivorous plants grow in acidic bogs, unproductive lakes, or sandy soils. These are all habitats that are poor in the nutrients that plants require for growth, particularly inorganic nitrogen, phosphorus, and calcium.

How much light do carnivorous plants need? In their native habitats many carnivorous plants live with full exposure to the sun. This is about 100,000 lux of light at noon. To grow these plants indoors requires a lot of light, not 100,000 lux but still a lot.

Carnivorous plants, as a general rule, grow best in sunny conditions. Many do well in partial sun. The nutrient-poor, soggy bogs provide bad conditions for most plants.

Few instances of direct mortality to either species have been documented. Instances of wolves killing bears and bears killing wolves have been reported, but such events are rare and considered the exception. According to Mech (1981), wolves sometimes kill bears, but likely only young, old, or otherwise weakened bears.

The grizzlies are more powerful, but the wolves are quicker and out-number the bear, says Smith. “It’s almost like the wolves are the mosquitoes buzzing around the bear’s head,” Smith says. “Although individual mosquitoes can’t overpower you, if there are enough of them, they’ll win.

“Grizzly bears are opportunistic hunters,” he said. “They will take advantage of any food source that presents itself.” Bears eating other bears isn’t entirely new—polar bears will eat each other, especially each others’ young. But for grizzlies it’s much more novel.

If any bear attacks you in your tent, or stalks you and then attacks, do NOT play dead—fight back! This kind of attack is very rare, but can be serious because it often means the bear is looking for food and sees you as prey. It is used defensively to stop an aggressive, charging, or attacking bear.

An ursid hybrid is an animal with parents from two different species or subspecies of the bear family (Ursidae). Species and subspecies of bear known to have produced offspring with another bear species or subspecies include black bears, grizzly bears and polar bears, all of which are members of the genus Ursus.

Fatal black bear attacks on humans are so rare — more so than any other species of bear — that they occur on average of once per year across North America, Garshelis said. In addition, about one black bear out of 1 million will attack a human in a predatory manner, Rogers said.

Two male grizzlies mated with the female polar bear to give rise to the four F1s, with one grizzly bear apparently mating with the polar bear in two different years (two of the F1s are full siblings, but born three years apart).

There are many sub-species of brown bear of varying sizes, but sticking with most well known sub species in North America, the brown bear wins. An American black bear at most will weigh six hundred pounds. Brown bears can weigh more than double that.

Why bears lose their fear of humans Bears are normally wary of people, but if a bear finds food without getting frightened away, he may come back for more. Each time this happens, he can become less fearful—and this habituation can lead to problems.

The results show that the elephant wears the crown in the animal kingdom – but only slightly. Elephants had a win rate of 74%, just fractions of a percent ahead of their single-horned cousins – the rhinoceros – in second place, also on 74%. Not far behind in third place is the grizzly bear, at 73%.

The consensus among experts is that the polar bear is the largest, but some believe the Kodiak bear to be larger.
