What adaptations does the silver fir tree have?

Answer 1

1. The conifer has needle-like leaves. This gives the conifer less surface area, meaning less water loss. 2. They produce pollen grains. This allows animals to deliver the pollen directly to female plant parts. 3. Seed- which is a plant embryo that is packaged with a food supply and can remain dormant for years until favorable conditions occur.

Answer 2

Some trees, such as ponderosa pine, can tolerate the hot, dry foothills where rain is limited. To reach water, a ponderosa seedling can grow a taproot two feet long within a few months of germinating. It can endure extremely high soil surface temperatures, but is easily killed by a heavy frost.

To withstand drought conditions, mature ponderosa pines have vigorous taproots reaching six feet into the soil and even down to 40 feet in rocky crevices. Side roots can radiate 150 feet. At lower elevations, these trees are widely spaced because their huge root systems compete for water. A ponderosa pine 80 to 100 feet tall requires as much as 400 gallons of water each day! Compare that to water usage of the average western household, which is about 250 to 300 gallons per day.

Spruce in the North Idaho high country can withstand severe cold.

In contrast to ponderosa pine, spruce is adapted to the short, cool summers and snowy winters of the high mountains. Spruce trees have shallow root systems, often penetrating less than two feet, since water is more readily available.

Unlike ponderosa pine, spruce are adapted to resist frosts any month of the year, but prolonged drought or high surface temperatures can kill spruce seedlings.

A: Evergreen trees have needles, instead of flat leaves, to survive winter hardship. Needles cut evaporation so trees can save water - dear in the winter. The narrow leaves manage this with three adaptations:

thicker skin, to retain water

a thicker coating of water-proof wax

simpler needle-like shape. The long, slender shape reduces leaf area, which, in turn, reduces the amount of water vapor escaping the leaf.

Trees grow wherever the rainfall exceeds water loss due to evaporation during the growing season and temperatures are above 50 degrees Fahrenheit much of the time. About 20 inches of annual rain does the trick although trees can get by with less rainfall where it is cooler and evaporation rates are less. Evergreens can cope with much less water than broadleaf trees. In the mountains, you can identify zones where the different trees can live.

Consider the Sandia Mountains in New Mexico. At 10,000 feet, the rainfall is about 30 inches and drops to less than 15 inches at the 14,000-foot summits.

Let's wander up the slopes and look at trees. We'll start off about 8000 feet in the Transitional Life Zone. Pines, firs, oaks, cottonwoods, birches, and maples abound. Climbing into the Canadian Zone around 10,000 feet, we can still find maple, alder, mountain ash and the like but also dense stands of spruce, firs, and pines.

We clamber into the Hudsonian Zone around 12,000 feet. Brrrr! It's cold. We see small deformed Engelmann spruce and stunted alpine fir. An occasional foxtail pine and alpine larch. No broadleaves. Not enough water. They can no longer survive; only hardy conifers with narrow needle-like leaves can make it.

Scrambling another thousand feet higher into the Alpine Zone, we survey land as bleak as the arctic barren grounds. No trees at all. Not enough water even for the evergreens.

That's why pine needles are narrow: to conserve meager water found up high or far north. By the way, the evergreens are the earliest seed plants to survive until modern times - virtually unchanged for more than 300 million years.

Answer 3

The balsam fir has at least one adaptation which is it's waxy resin like coating on the needles. They help to preserve water.

Answer 4

One adaptation is their waxy coaing and small surface area which minimize water loss and resist cold temperatures

Answer 5

Balsam fir trees survive because they can survive in many different climates. They also have dormant seeds to ensure future survival.

Answer 6

The tree adapts by growing tall enough to reach more sunlight which provides for it food and warmth. It falls under kingdom plantae.

Answer 7

It has longer roots
