13. In a forest, why do you rarely see young pine trees growing under a broad-leaved tree, such as a maple? If broad-leaved trees eventually take over a forest as pines die off, how does that affect other organisms living in the forest? How does it affect this forest ecosystem?*​

Answers

Answer 1

Answer:/Explanation:

Broad leaved trees would block the sunlight due to the size of their leaves. This would reduce the amount of sunlight that the pine tree could absorb, and would therefore inhibit its ability to efficiently perform photosynthesis. This would reduce the amount of food it could synthesise, and interfere with its growth and reproduction.

Without pine trees, the diversity of the ecosystem would be reduced. Several organisms rely on pine seeds and leaves as a food source. In the absence of pine trees, competition for other food sources could increase, and certain birds, squirrels etc. could die off.

Pine trees are also a habitat for many birds and small creatures. Without these trees, these animals could struggle to find efficient shelter.

Each year, the United States' federal costs exceed the anticipated national budget. In fact the last time that the United States government was able to end a fiscal year without accruing more debt was in 1960. This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades. The table shown below lists the recorded U.S. national debt amounts, written in standard form, for each decade, from 1960 to the year 2010.


Year U.S. national debt (in U.S. dollars)

1960 $286,330,760,848.37

1970 $370,918,706,949.93

1980 $907,701,000,000.00

1990 $3,233,313,451,777.25

2000 $5,674,178,209,886.86

2010 $13,561,623,030,891.79

For each decade, convert the U.S. national debt amount to a number in scientific notation, rounded to the nearest hundred millions dollars. Enter in numerical answers only.

What is chemical changes?

A chemical change is the transformation of one substance into another, the emergence of new compounds with distinct properties, or any combination of these.

It happens when two compounds mixes to create a new material (synthesis or either decomposes to form more substances).

Chemical synthesis, or, alternatively, chemical breakdown into two or more separate molecules, occurs when one material reacts with another to create a new substance.

These processes are referred to as chemical reactions, and they are typically irreversible barring additional chemical reactions.

Therefore, burning of wooden logs and formation of water is an example of chemical changes.

Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.

Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY

Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.

Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.
