Chemosynthetic organisms are considered **autotrophs**. They produce their own food using chemical energy, typically from inorganic compounds, rather than relying on sunlight or organic materials.

Plants prevent erosion primarily because **roots hold soil in place**. The root systems of plants help anchor the soil, reducing the likelihood of erosion from wind and water.

Plants use **water and carbon dioxide** to convert the sun’s energy during the process of photosynthesis. They take in carbon dioxide from the air and water from the soil and utilize sunlight to produce glucose and oxygen.

When plants convert the sun's energy during photosynthesis, they create **glucose**. In addition to glucose, oxygen is also produced as a byproduct.
Heterotrophs can be primary, secondary, or tertiary consumers. The amount of energy they consume is directly related to what they eat. Put the following heterotrophs in order from highest amount of energy to lowest amount of energy.(1 point)

The correct order from the highest amount of energy to the lowest amount of energy is: **herbivore, omnivore, carnivore**.
Herbivores generally consume plants (primary producers) and therefore have more energy available to them. Omnivores eat both plants and animals, while carnivores primarily consume other animals, which typically results in a loss of energy at each trophic level.

To find the amount of energy available to secondary consumers, we can use the information provided about energy transfer between trophic levels.
1. **Primary Producers:** 30,000 kcal
2. **Primary Consumers (herbivores):** Only 10% of the energy from primary producers is transferred, so:
\[
\text{Energy available to primary consumers} = 30,000 \, \text{kcal} \times 0.10 = 3,000 \, \text{kcal}
\]
3. **Secondary Consumers (carnivores):** Again, only 10% of the energy from primary consumers is transferred to secondary consumers, so:
\[
\text{Energy available to secondary consumers} = 3,000 \, \text{kcal} \times 0.10 = 300 \, \text{kcal}
\]
Therefore, the amount of energy available to secondary consumers is **300 kcal**.
1. **Primary Producers:** 30,000 kcal
2. **Primary Consumers (herbivores):** Only 10% of the energy from primary producers is transferred, so:
\[
\text{Energy available to primary consumers} = 30,000 \, \text{kcal} \times 0.10 = 3,000 \, \text{kcal}
\]
3. **Secondary Consumers (carnivores):** Again, only 10% of the energy from primary consumers is transferred to secondary consumers, so:
\[
\text{Energy available to secondary consumers} = 3,000 \, \text{kcal} \times 0.10 = 300 \, \text{kcal}
\]
Therefore, the amount of energy available to secondary consumers is **300 kcal**.
