What ecosystems are aquatic?
Oceans, sea , rivers and other water bodies are the ecosystems that are referred to as aquatic. The ecosystems that are aquatic are freshwater and saltwater(marine).
What can coastal and marine ecosystems be protected by avoiding?
overfishing
Is overfishing still a problem?
yes
What nutrient is most often limiting in aquatic ecosystems?
The nutrient most often limiting in aquatic ecosystems is phosphorus.
What are 4 ways that humans affect aquatic ecosystems?
Humans impact aquatic ecosystems through pollution, such as runoff from agriculture and industry that introduces harmful chemicals and nutrients, leading to issues like eutrophication. Overfishing depletes fish populations and disrupts food webs, while habitat destruction, such as dam construction and coastal development, alters natural environments. Additionally, climate change contributes to rising water temperatures and altered salinity, further stressing aquatic habitats and species.
What affects the coral reef's ecosystems?
Waves shape them and also provide the needed oxygen
When did overfishing become a problem?
Overfishing became a significant problem in the mid-20th century, particularly after World War II, as advancements in fishing technology allowed for increased catch efficiency. This led to the depletion of many fish stocks, particularly in industrialized nations. By the 1970s and 1980s, the consequences of overfishing became more evident, prompting international discussions on sustainable fishing practices and conservation efforts. The issue has continued to escalate, affecting marine ecosystems and global food security.
What are four main factors that affect aquatic ecosystems?
The four main factors that affect aquatic ecosystems are waters depth, temperature, flow, and amount of dissolved nutrients.
How are aquatic ecosystems determined?
An Aquatic system is determined by depth, flow, temperature, and chemistry of the overlying area.
How does overfishing affect the dolphins?
well a dolphin could get a plastic can ring stuck on his throat and die from suffocate caused by the plastic can ring.
How are people harming estuaries?
People harm estuaries through pollution, habitat destruction, and overfishing. Agricultural runoff introduces harmful chemicals and nutrients, leading to algal blooms that deplete oxygen and harm aquatic life. Urban development often results in the loss of wetlands, which serve as critical buffers and nurseries for marine species. Additionally, overfishing disrupts the ecological balance, threatening the health of these vital ecosystems.
What microorganisms are capable of photosynthesis and found in aquatic ecosystems?
Phytoplanktons
