Biology Review EOY

Read the passage and answer the following question(s). The food web represents interactions in East Texas. Use the food web to answer any questions that follow.

What keeps matter from deceased organisms from accumulating?

• Matter is slowly transferred from decomposers to producers, and consumers take in the remains of both types of organisms.

• Matter is rapidly transferred from producers to consumers, and remains from both types of organisms are taken in by decomposers.

• Matter is slowly transferred from the Sun to consumers, and consumers assist decomposers in taking in the remains of producers.

• Matter is rapidly transferred from the Sun to decomposers, and remains from decomposers are taken in by producers.

This food web reveals that, as matter flows through trophic levels, —

• matter from consumers, such as the green lynx spider, is eventually recycled by decomposers, such as a fungus.

• matter from producers, such as the cutleaf daisy, is immediately recycled by decomposers, such as a bacterium.

• matters from all organisms, such as the Bald eagle, is dissipated at each level and none of it is recycled.

• matter from the Sun is recycled after many years by consumers, such as a Bachman's sparrow.

Explain the role of salivary glands in the process of nutrient absorption.

Which organ is responsible for the final round of chemical breakdown of food using enzymes from the pancreas and bile from the liver?

• Stomach

• Small intestine

• Large intestine

• Esophagus

What is the primary function of the large intestine in the digestive system?

• Absorbing nutrients

• Reabsorbing water and vitamins

• Breaking down food

• Releasing enzymes

Describe the process that occurs in the stomach during digestion.

How do beneficial bacteria in the large intestine contribute to the digestive process?

Which system MOST interacts with the digestive system to physically help move food through the digestive tract?

• Skeletal system

• Circulatory system

• Muscular system

• Endocrine system

The small intestine is covered with fingerlike projections called villi. Each singular villus contains blood and lymph vessels. Identify which system is interacting with the digestive system within the villi, and provide a benefit of the interaction.
