What else can I help you with?
What is the initial food source for most terrestrial ecosystems?
The initial food source for most terrestrial ecosystems is typically plants. Plants produce their own food through photosynthesis, which forms the base of the food chain for animals and other organisms in the ecosystem.
What do most terrestrial organisms reproduce by?
Internal fertilization .
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 kind of radiation do living organisms depend on?
-- All depend on heat. -- Most depend on light. -- Those in specialized occupations, such as microwave engineers, radio announcers, and tanning salon proprietors, depend on other bands of EM.
Plants are the main producers in most land what?
Plants are the main producers in most terrestrial ecosystems, converting sunlight into energy through photosynthesis. They are crucial in the food chain as they provide food and oxygen for other organisms to survive. Their presence helps support a diverse range of life on land.
Why gymnosperms considered as the most successful terrestrial plants compared to other plants?
They aren't. Angiosperms are usually considered the most successful land plants.
Are there organisms that do not rely on other organisms for food?
Most plants.
Why do all living things depend on green plants?
Living organism depend on plants because of the plants capability to do photosynthesis. Photosynthesis is converting the sun energy into a glucose type sugar. Sugar is a type of energy that all living organisms need.
What do most organisms eat?
most organisms either eat meat or both plants and meat (omnivorous)!
The ultimate source of all energy in a terrestrial ecosystem is?
The ultimate source of all energy in a terrestrial ecosystem is the sun. Plants capture this solar energy through photosynthesis and convert it into chemical energy, which is then passed on to other organisms in the ecosystem through the food chain.
What cell would you expect to find only in autotrophic organisms?
Autotrophic organisms are animals or plants that can create their own energy from the Sun. The organelle most common in these organisms are chloroplasts.
Why is sunlight an important abiotic factor in all terrestrial ecosystems?
Sunlight is essential for photosynthesis, the process by which plants produce energy-rich organic compounds. This process provides the energy source for most terrestrial ecosystems. Sunlight also regulates temperatures and influences patterns of rainfall, which can in turn affect the types of organisms that can survive in a particular environment.
