Summary Introduction

To determine: The effect of the structure of the digestive tract in different invertebrates on the size of the organism they can eat.

Introduction:

The invertebrates are those organisms that lack a back bone. Every organism has a different method of digestion depending on the structure of their digestive system. For example, the sponges have a filter feeding mechanism in which they take up water from the surrounding in their siphons and filters it to obtain microbes or nutrient particles and utilize it as a source of food.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
