How far are We from Mass Extinction

Something was killing the frogs of Central America, and pretty fast. One of the first people to notice was Karen Lips, an American studying amphibians in a rainforest there. In 1993, she was shocked to discover that dozens of frogs had vanished from her research site in Costa Rica. When she moved to Panama to continue her research, she found that the frogs there were dying too. And no one could explain why.

By 2006, whatever was killing the frogs had swept across central Panama. Within a few years, dozens of amphibians had disappeared from the wild, including the Panamanian golden frog, famous for being so toxic that the poison on the skin of just one animal can kill 1,000 mice.

The recent demise of the frog and the other amphibians in Central America is just part of a large phenomenon that’s being called the Sixth Extinction.

Today, extinction rates among nearly all the groups of plants and animals are soaring. A century from now, pandas, tigers, and rhinos may exist only in zoos. Scientists say that within this century, 20 to 50 percent of all plant and animal species might disappear.

Under normal circumstances, species rarely become extinct. Scientists estimate that one amphibian species disappears every 1000 years. But sometimes, the world changes very suddenly. In these rare moments, species disappear much more quickly. These events are known as mass extinctions and scientists say that we may be headed toward one.

Science-Lesson 1-Chapter 12 Notes

Chapter 12 Lesson 1

• Transpiration- loss of water vapor through stomata of a leaf
• Photosynthesis- the process in which plants use light energy to produce food.
• Respiration- the process by which organisms break down food to release energy.
• Carbon dioxide needed for photosynthesis enters leaves through the stomata. Water vapor escapes during this process.
• Chlorophyll in plants captures sunlight. Photosynthesis splits the water molecules and makes glucose and oxygen, which are needed by all organisms.
• Through respiration, energy stored in glucose becomes available for cell activities.

Each stomata is surrounded by two guard cells that control the size of the opening. Water moves into the cell and out of the cell by osmosis. When guard cells absorb water, they swell and the stomata opens, letting carbon dioxide in. Water vapor escapes during the process. When guard cells absorb water, they swell and the stomata opens, letting carbon dioxide. Water vapor escapes during the process. When guard cells lose water, they relax and the stomata closes.

Chlorophyll is a pigment that traps light energy from plants to use in making food. Photosynthesis is the process in which plants use light energy to make their own food.

During photosynthesis, a plant makes food from light energy, carbon dioxide, and water in a series of chemical reactions. Some of the light energy trapped in the chlorophyll is used to split water molecules into hydrogen and oxygen. Light energy is then used to join hydrogen and carbon dioxide together to form a new sugar molecule. The sugar formed is used to form glucose, the food a plant uses for maintenance and growth. The process is illustrated in the following equation:

6CO2 + 6H2O + light energy = chlorophyll, sugar, and oxygen

Respiration is the process by which organisms break down food to release energy. Respiration that uses oxygen to break down food chemically is called aerobic respiration. Cellular respiration occurs in the mitochondria of all eukaryotic cells. Plant and animals need energy to build up and repair their cells, tissues, and organs. Sugar produced during photosynthesis by plant cells is used to make cellulose to build wall cells. Plants also use energy from the food they make during photosynthesis for growth and reproduction.

How to Find the Probability

Probability

Probability is the measure of how likely an event is to occur. It is expressed as a number between 0 and 1. Probabilities can be impossible, unlikely, somewhat likely, unlikely, highly likely, or certain.

A fish tank has 40 orange fish, 4 blue fish, and 6 black fish. A fish is chosen from the tank at random. Describe the likelihood that the chosen fish will be a) orange or b) yellow.

Most of the fish are orange. Only a few are either blue or black. So, it is highly likely that an orange fish will be chosen.

None of the fish are yellow. So, it is impossible that one will be chosen.

To find the probability, P, of an event where each outcome is equally likely, use this formula:

P=number of favorable outcomes/number of possible outcomes

This chart describes the fish in the tank.

	Solid Color	Striped
Orange	35	5
Blue	4	0
Black	2	4

What is the possibility that a fish chosen at random from the tank will be a striped orange fish?

The number of favorable outcomes is the number of striped orange fish: 5.

The number of possible outcomes is the total number of fish in the tank: 35+5+4+2+4=50

Write the number of favorable outcomes over the possible outcomes.

The probability of choosing a striped orange fish is 1/10
