Ultimate source of energy for terrestrial ecosystems?
The ultimate source of energy for terrestrial ecosystems is sunlight. Plants capture sunlight and convert it into chemical energy through photosynthesis, which is then passed on to consumers in the food chain. Without sunlight, photosynthesis cannot occur, and the ecosystem would not have the energy needed to sustain life.
What is the primary source of energy for the hydrothermal vents?
The primary source of energy for hydrothermal vents is chemosynthesis, where bacteria use chemicals such as hydrogen sulfide to produce energy instead of sunlight. These bacteria form the base of the food chain at hydrothermal vents, supporting unique ecosystems.
What would happen to life on earth if there were no soil?
If there were no soil on Earth, life as we know it would cease to exist. Soil is essential for plant growth, which is the basis of all terrestrial food chains. Without soil, plants would not be able to grow, leading to a collapse of ecosystems and the extinction of most life forms.
What organism is being affected by littering?
Many organisms are affected by littering, especially marine animals like sea turtles, seabirds, and marine mammals. These animals can become entangled in litter or mistakenly ingest it, leading to injury or death. In terrestrial ecosystems, littering can harm animals by altering their habitat and food sources.
What role do diatms have in nature?
Diatoms play a crucial role in ecosystems as they are primary producers that form the base of the food chain. They are efficient at photosynthesis, producing a significant portion of the world's oxygen and serving as a source of food for a variety of organisms. Diatoms also contribute to nutrient cycling and are indicators of water quality.
What is the initial source of food in most ocean and freshwater ecosystems?
Phytoplankton.
Ultimate source of energy for terrestrial ecosystems?
The ultimate source of energy for terrestrial ecosystems is sunlight. Plants capture sunlight and convert it into chemical energy through photosynthesis, which is then passed on to consumers in the food chain. Without sunlight, photosynthesis cannot occur, and the ecosystem would not have the energy needed to sustain life.
The organisms that are classified as primary consumers are the?
organisms that feed on producers and are typically herbivores, consuming plants or algae as their main food source. Examples include rabbits, deer, and grasshoppers in terrestrial ecosystems, and zooplankton in aquatic ecosystems.
What are the producers in a terrestrial ecosystem Aquatic ecosystem?
Plants make up the majority of production in terrestrial ecosystems.
Algae and green plants are first in what food chain?
Algae and green plants are primary producers in the food chain, forming the base of many aquatic and terrestrial ecosystems. They convert sunlight into energy through photosynthesis, serving as a crucial energy source for consumers higher up in the food chain.
Why marine food chain can have more than 5 trophic levels?
food webs ... and because in marine ecosystems, there are phytoplankton as well. These microorggansims are not apparant in terrestrial food chains
What plants live in the terrestrial ecosystem?
Plants that live in terrestrial ecosystems include trees, shrubs, grasses, and other vegetation that grow on land. These plants are adapted to living in soil and typically obtain nutrients and water from the ground. They play a crucial role in supporting terrestrial ecosystems by providing food, oxygen, and habitat for various organisms.
What are the limiting factors that affect the biodiversity and productivity of both terrestrial and aquatic ecosystems?
Limiting factors that affect biodiversity and productivity in terrestrial and aquatic ecosystems include availability of resources like food and water, habitat destruction, pollution, climate change, and invasive species. These factors can disrupt the balance of ecosystems and reduce the variety of species that can thrive in them.
What are two organisms are at the top of the food web?
Two organisms that are commonly at the top of the food web are apex predators such as lions in terrestrial ecosystems and great white sharks in marine ecosystems. These organisms have few or no natural predators and play a crucial role in regulating the populations of other organisms in their respective ecosystems.
What would have most likely occurred if plants had not begun to live on land?
If plants had not evolved to live on land, it is likely that terrestrial ecosystems would have remained dominated by non-plant organisms such as fungi, bacteria, and algae. This would have drastically altered the development of terrestrial ecosystems and likely impacted the evolution of animals that rely on plants for food and habitat.
What is the energy source of ALL ecosystems?
The energy source of all ecosystems is sunlight. Sunlight is captured by plants through photosynthesis, which converts it into chemical energy that is then passed on to other organisms through the food chain.
What can you conclude about the importance of marine ecosystems to global food webs and the biosphere?
Since marine ecosystems cover over 70% of the Earth's surface, theimportance of these ecosystems on our global food web is monumental.
