the second animal found is the polar bear
a boundary for a subwatershed denoted by a third order stream
The bifurcation ration is the relationship between the number of steams of one order an those of the next highest order. It is calculated by dividing the number of streams in one order by the number in the next order. For example , in a basin :N1/N2 = (number of the first order streams / number of second order streams) = 20/4 = 5N2/N3 = (number of the second order streams / number of third order streams) = 4/2 = 2N3/N4 = (number of the third order streams / number of fourth order streams) = 2/1 = 2then, by finding the mean of each rations in the basin being studied :(5 + 2 + 2)/3 = 3 = bifurcation ration for this basin.*** the significance of this ratio is that as the ration is reduced so the risk of flooding within the basin increases. it also indicates the flood risk for parts of the basin.
A caddis fly is an insect of the order Trichoptera with two pairs of hairy wings, found near lakes and streams.
Stream order is a method of classifying the hierarchy of streams within a drainage basin based on their size and connectivity. The system, developed by Horton and Strahler, assigns a numerical value to streams: first-order streams are the smallest, with no tributaries, while higher-order streams form when two streams of the same order converge. This classification helps in understanding the ecological and hydrological characteristics of a watershed. The stream order increases as streams merge, reflecting the complexity of the drainage network.
All rivers are streams but not all streams are rivers. There is a defined method (Link) of sizing flowing water, all these features are streams and are ranked as 1st through 12th order streams. The systems starts with what would be called in non-scientific terms brooks and works up to rivers. Going up in size and strength, streams that are classified as 4th through 6th order are medium streams while anything larger is a river. Examples:The Ohio River in the United States is an 8th order streamThe Mississippi River is a 10th order stream.The Amazon in South America, is a 12th order stream.
Primates include: Human Chimpanzee Gorilla Monkeys Lemurs
You add the number of streams that branch off the main stream which is the first order then you add the number of streams branching off that stream whih becomes the 2nd order and the sum of the no. of stream orders divided by the number of streams gives the bifurcation ratio.

Snakes are considered third order heterotrophs because they consume other animals (second order heterotrophs) as their primary food source to obtain energy.
Well, you have big animals, medium animals & then small animals, in that order.
The streams and rivers would incise (cut down into) the land in order to achieve their desired gradient.
A producer may mean an organism that produces its own energy. This means a plant, as they produce energy in the form of sugars from water, CO2 and UV light. A consumer that only eats plants would be a herbivore (an animal that only eats plants), or a fungi that only digests rotting plants.
