Explanation:

To complete this CER (Claim - Evidence - Reasoning) for the question "How do hurricanes impact ecosystems?":

Claim:

Hurricanes impact ecosystems by causing physical damage, altering habitats, and disrupting ecological processes.

Evidence 1:

Hurricanes can uproot trees and destroy vegetation. For example, after Hurricane Katrina, large areas of coastal forests in Louisiana were devastated, with many trees being uprooted or broken.

Reasoning 1:

This evidence is important because vegetation is a key component of ecosystems, providing food and shelter for many organisms. The loss of vegetation can lead to a decline in populations of herbivores and the predators that depend on them, disrupting the food web.

Evidence 2:

Hurricanes often cause storm surges that flood coastal areas with saltwater. In some cases, this saltwater intrusion can kill freshwater plants and animals in wetlands. For instance, after Hurricane Sandy, saltwater from the storm surge damaged freshwater marshes in New Jersey, killing many freshwater - dependent species.

Reasoning 2:

This evidence matters as wetlands are important ecosystems that act as nurseries for many aquatic species, filter pollutants, and protect shorelines. Damage to wetlands can have long - term consequences for water quality and the survival of many species.

Evidence 3:

Hurricanes can displace or kill large numbers of animals. Birds may be blown off course during a hurricane, and marine animals like fish can be stranded or killed due to changes in water conditions (such as rapid changes in temperature or salinity) caused by the hurricane. After Hurricane Andrew, many wildlife populations in the affected areas, including the Florida Panther, were negatively impacted due to habitat destruction and direct mortality.

Reasoning 3:

This evidence is significant because the loss or displacement of animal populations can disrupt ecological relationships, such as pollination (if pollinators are affected) or predator - prey dynamics, and can also lead to a loss of biodiversity in the affected ecosystems.

CER Statement:

Hurricanes impact ecosystems by causing physical damage, altering habitats, and disrupting ecological processes (Claim). Evidence shows that hurricanes can uproot trees and destroy vegetation (e.g., after Hurricane Katrina), cause saltwater intrusion that harms freshwater ecosystems (e.g., after Hurricane Sandy), and displace or kill large numbers of animals (e.g., after Hurricane Andrew) (Evidence). These impacts are important because vegetation loss disrupts food webs, saltwater intrusion damages important wetland ecosystems, and animal displacement/killing disrupts ecological relationships and reduces biodiversity (Reasoning).

Answer:

Claim:

Hurricanes impact ecosystems by causing physical damage, altering habitats, and disrupting ecological processes.

Evidence 1:

Hurricanes can uproot trees and destroy vegetation (e.g., Hurricane Katrina's impact on Louisiana's coastal forests).

Reasoning 1:

Vegetation loss disrupts food webs by reducing resources for herbivores and their predators.

Evidence 2:

Hurricanes cause saltwater intrusion that harms freshwater ecosystems (e.g., Hurricane Sandy's impact on New Jersey's freshwater marshes).

Reasoning 2:

Wetland damage affects water quality and species survival.

Evidence 3:

Hurricanes displace or kill animals (e.g., Hurricane Andrew's impact on Florida Panther and other wildlife).

Reasoning 3:

Animal population changes disrupt ecological relationships and reduce biodiversity.

CER Statement:

Hurricanes impact ecosystems by causing physical damage, altering habitats, and disrupting ecological processes. Evidence includes vegetation destruction (Hurricane Katrina), saltwater - related wetland damage (Hurricane Sandy), and animal displacement/mortality (Hurricane Andrew). These impact ecosystems as they disrupt food webs, harm wetland functions, and reduce biodiversity.
